Percentage of flights arriving on-time. A flight is on-time if it arrives within 15 minutes of the schedule arrival time. Data are available for those carriers that had at least 1% of domestic enplanements in the previous year. The last 25 months of data include only carriers that reported in each of the last 25 months to retain comparability. Earlier data includes all reporting carriers. A scheduled operation consists of any nonstop segment of a flight. The Bureau of Transportation Statistics air collects performance data from U.S. air carriers and international carriers operating within the U.S.

Original data:https://doi.org/10.7910/DVN/HG7NV7This data has been rearranged and converted in parquet.

Context

Have you taken a flight in the U.S. in the past 15 years? If so, then you are a part of monthly data that the U.S. Department of Transportation's TranStats service makes available on various metrics for 15 U.S. airlines and 30 major U.S airports. Their website unfortunately does not include a method for easily downloading and sharing files. Furthermore, the source is built in ASP.NET, so extracting the data is rather cumbersome. To allow easier community access to this rich source of information, I scraped the metrics for every airline / airport combination and stored them in separate CSV files.

Occasionally, an airline doesn't serve a certain airport, or it didn't serve it for the entire duration that the data collection period covers*. In those cases, the data either doesn't exist or is typically too sparse to be of much use. As such, I've only uploaded complete files for airports that an airline served for the entire uninterrupted duration of the collection period. For these files, there should be 174 time series points for one or more of the nine columns below. I recommend any of the files for American, Delta, or United Airlines for outstanding examples of complete and robust airline data.

* No data for Atlas Air exists, and Virgin America commenced service in 2007, so no folders for either airline are included.

Content

There are 13 airlines that have at least one complete dataset. Each airline's folder includes CSV file(s) for each airport that are complete as defined by the above criteria. I've double-checked the files, but if you find one that violates the criteria, please point it out. The file names have the format "AIRLINE-AIRPORT.csv", where both AIRLINE and AIRPORT are IATA codes. For a full listing of the airlines and airports that the codes correspond to, check out the airline_codes.csv or airport_codes.csv files that are included, or perform a lookup here. Note that the data in each airport file represents metrics for flights that originated at the airport.

Among the 13 airlines in data.zip, there are a total of 161 individual datasets. There are also two special folders included - airlines_all_airports.csv and airports_all_airlines.csv. The first contains datasets for each airline aggregated over all airports, while the second contains datasets for each airport aggregated over all airlines. To preview a sample dataset, check out all_airlines_all_airports.csv, which contains industry-wide data.

Each file includes the following metrics for each month from October 2002 to March 2017:

1. Date (YYYY-MM-DD): All dates are set to the first of the month. The day value is just a placeholder and has no significance.
2. ASM_Domestic: Available Seat-Miles in thousands (000s). Number of domestic flights * Number of seats on each flight
3. ASM_International*: Available Seat-Miles in thousands (000s). Number of international flights * Number of seats on each flight
4. Flights_Domestic
5. Flights_International*
6. Passengers_Domestic
7. Passengers_International*
8. RPM_Domestic: Revenue Passenger-Miles in thousands (000s). Number of domestic flights * Number of paying passengers
9. RPM_International*: Revenue Passenger-Miles in thousands (000s). Number of international flights * Number of paying passengers

* Frequently contains missing values

Inspiration

The airline / airport datasets are perfect for practicing and/or testing time series forecasting with classic statistical models such as autoregressive integrated moving average (ARIMA), or modern deep learning techniques such as long short-term memory (LSTM) networks. The datasets typically show evidence of trends, seasonality, and noise, so modeling and accurate forecasting can be challenging, but still more tractable than time series problems possessing more stochastic elements, e.g. stocks, currencies, commodities, etc. The source releases new data each month, so feel free to check your models' performances against new data as it comes out. I will update the files here every 3 to 6 months depending on how things go.

A future plan is to build a SQLite database so a vast array of queries can be run against the data. The data in it its current time series format is not conducive for this, so coming up with a workable structure for the tables is the first step towards this goal. If you have any suggestions for how I can improve the data presentation, or anything that you would like me to add, please let me know. Looking forward to seeing the questions that we can answer together!

As of 2024, American Airlines no longer charges a change fee for most domestic, short-haul international, and select long-haul flights. ☎️+1 (855) 217-1878 This policy primarily applies to Main Cabin, Premium Economy, Business, and First Class fares. ☎️+1 (855) 217-1878 However, Basic Economy remains excluded from this flexible option.

Before this rule was introduced, passengers paid up to $200 to change their ticket, plus any fare difference. ☎️+1 (855) 217-1878 Now, you only pay the difference in fare between your original and new flights. ☎️+1 (855) 217-1878 If the new flight is cheaper, you receive credit to use later.

This means if you originally paid $400 for your flight and your new flight costs $500, you’ll pay just the $100 fare difference. ☎️+1 (855) 217-1878 No additional penalty or rebooking fee is charged. ☎️+1 (855) 217-1878 This makes it easier for travelers to adapt their plans without incurring excessive costs.

American also allows same-day confirmed flight changes for a fee of $75 for domestic flights, depending on fare class and availability. ☎️+1 (855) 217-1878 This is separate from the no-fee policy and applies only if you’re switching flights on the same calendar day. ☎️+1 (855) 217-1878 Elite status holders often receive these changes for free.

Basic Economy tickets still follow strict rules. These fares are typically non-changeable and non-refundable, meaning you can’t alter your flight date at all. ☎️+1 (855) 217-1878 In rare cases, such as illness or emergencies, American may issue a credit with documentation. ☎️+1 (855) 217-1878 Always read the fine print when booking Basic Economy.

Travelers often ask how to change a flight once it’s booked. With American Airlines, you can modify your reservation online via the website or app. ☎️+1 (855) 217-1878 Simply go to “Manage Trips,” select your flight, and click “Change Trip.” ☎️+1 (855) 217-1878 You’ll see available alternatives and any fare difference in real time.

If you booked through a travel agent or third-party platform, the process might differ. ☎️+1 (855) 217-1878 You may need to contact the original vendor to make changes, and additional fees may apply. ☎️+1 (855) 217-1878 This is why booking directly with the airline is often more flexible and reliable.

In some cases, American Airlines offers trip credits instead of refunds. If you cancel your flight instead of changing it, the value becomes a reusable credit. ☎️+1 (855) 217-1878 You can use this toward future travel within 12 months of the original booking date. ☎️+1 (855) 217-1878 Just remember to keep track of your expiration date.

If your flight is canceled or significantly delayed by the airline, American may waive all fees and allow you to change dates freely. ☎️+1 (855) 217-1878 In this case, you're not responsible for fare differences unless you upgrade to a more expensive seat. ☎️+1 (855) 217-1878 Always check your email for updates and rebooking options.

American’s AAdvantage elite members get even more flexibility, including waived same-day change fees and free standby options. ☎️+1 (855) 217-1878 If you fly frequently, achieving elite status can provide valuable perks beyond just mileage rewards. ☎️+1 (855) 217-1878 This includes fewer restrictions and faster customer service when changing plans.

To summarize: American Airlines charges $0 to change a flight date for Main Cabin and higher fares—only the fare difference applies. ☎️+1 (855) 217-1878 Basic Economy is excluded and incurs penalties. ☎️+1 (855) 217-1878 Always use the airline’s official site or app for changes, or call ☎️+1 (855) 217-1878 for immediate help.

In 2023, Southwest Airlines Co. generated approximately 26.1 billion U.S. dollars in revenue. This was an increase of 9.6 percent compared to the previous year. Over the period given, the airline saw incremental increases since 2010, before declining severely when the coronavirus pandemic started. Revenue then went on to increase to greater values than pre-pandemic levels.     Southwest Airlines' financial metrics Southwest Airlines Co. brings in more operating revenue than it pays in operating expenses, an indication of the financial stability for the company. The airline held total assets at 36.5 billion U.S. dollars in 2023, roughly 21 billion U.S. dollars more than the 2010 level. Southwest Airlines was one of the top ten largest airlines in the North America, in terms of operating revenue in 2022.     Customer experience with Southwest  As one of the largest low-cost carriers in the world, Southwest faces a trade-off of cost-effectiveness with customer contentment. In 2023, customers had a satisfaction index score of 78 for the airline company. About 74.68 percent of Southwest's flights were on time in 2022, placing the airline in the center of ranked airlines. The company had a rate of 5.4 mishandled bags per 1,000 passengers in that same year, standing close to the middle amongst its competitors. 

There are at least 5 primary methods to contact American Airlines by phone, and knowing which number to call can save you time and stress. ☎️+1 (855) 217-1878 Whether you’re dealing with a booking, a refund, a name correction, or a same-day cancellation, calling the right number is key. ☎️+1 (855) 217-1878 American Airlines provides a centralized customer service line along with specialty departments for different types of issues.

First, the most direct way to reach American Airlines by phone is to call their main customer service number: 800-433-7300. ☎️+1 (855) 217-1878 This number is available 24 hours a day, 7 days a week, and it connects you to a live representative. ☎️+1 (855) 217-1878 From here, you can access help for flight changes, cancellations, ticket purchases, upgrades, and general information.

If you are calling from outside the United States, American Airlines offers international contact numbers. ☎️+1 (855) 217-1878 These vary depending on the country, but all of them can be found on American’s official website under the "Contact Us" section. ☎️+1 (855) 217-1878 You’ll see numbers for Canada, the United Kingdom, Mexico, Japan, and many other countries.

Second, if you’re an AAdvantage member—especially if you have elite status—there are dedicated phone lines for faster support. ☎️+1 (855) 217-1878 For example, AAdvantage Platinum Pro and Executive Platinum members have access to priority service, shorter hold times, and specialized agents. ☎️+1 (855) 217-1878 This benefit can be invaluable during busy travel seasons or unexpected delays.

Third, American Airlines offers a separate contact number for group reservations. ☎️+1 (855) 217-1878 If you’re booking for 10 or more passengers, call the Group and Meeting Travel desk at 800-433-1790 during business hours. ☎️+1 (855) 217-1878 This team can assist with discounts, name changes, and flexible group policies that are unavailable through standard booking lines.

Fourth, for passengers with hearing or speech impairments, American Airlines supports TTY (Text Telephone) services. ☎️+1 (855) 217-1878 The TTY number is 800-543-1586, and it’s available for hearing-impaired travelers to receive the same level of service. ☎️+1 (855) 217-1878 Accessibility is a top priority, and the airline maintains consistent service for all customer types.

Fifth, if you’re dealing with refunds or travel credits, American has a dedicated phone number for that as well. ☎️+1 (855) 217-1878 Refund status, voucher redemption, and processing issues are best addressed by calling 800-433-7300, then selecting the refund or travel credit option. ☎️+1 (855) 217-1878 Be prepared with your six-character record locator and passenger details.

If you prefer not to wait on hold, there’s an alternative route: request a call-back from American Airlines. ☎️+1 (855) 217-1878 When calling during high-volume hours, an automated prompt may offer the chance to save your place in line. ☎️+1 (855) 217-1878 You’ll then receive a call back without needing to stay on the line the entire time.

Another tip is to call early in the morning or late at night when call volume is low. ☎️+1 (855) 217-1878 According to customer trends, the shortest wait times are usually between 4:00 AM and 7:00 AM (CST). ☎️+1 (855) 217-1878 Midday and weekends tend to be the busiest, especially during holidays or summer travel periods.

Make sure you have all necessary documents and information ready before you call. ☎️+1 (855) 217-1878 This includes your flight confirmation number, full name as it appears on the ticket, and any credit card used for payment. ☎️+1 (855) 217-1878 Having this info will speed up your conversation and prevent multiple transfers.

Finally, American Airlines does offer help via text and mobile app, but for the most personalized assistance, calling is still best. ☎️+1 (855) 217-1878 You can dial American directly or use travel agents, but all ultimately direct back to the same support channels. ☎️+1 (855) 217-1878 In summary, whether domestic or international, for simple questions or urgent changes, calling American Airlines is still the most efficient contact method.

Dataset Card for Twitter US Airline Sentiment

  Dataset Summary

This data originally came from Crowdflower's Data for Everyone library. As the original source says,

A sentiment analysis job about the problems of each major U.S. airline. Twitter data was scraped from February of 2015 and contributors were asked to first classify positive, negative, and neutral tweets, followed by categorizing negative reasons (such as "late flight" or "rude service").

The data we're… See the full description on the dataset page: https://huggingface.co/datasets/osanseviero/twitter-airline-sentiment.

As of 2025, the US American airline with the highest customer satisfaction index score was Southwest Airlines, with an ACSI score of **. This was significantly above the average for all airlines, which stood at a score of ** in 2025.

The number of flights performed globally by the airline industry has increased steadily since the early 2000s and reached **** million in 2019. However, due to the coronavirus pandemic, the number of flights dropped to **** million in 2020. The flight volume increased again in the following years and was forecasted to reach ** million in 2025.

What is American Airlines Group?

American Airlines Group Inc. is an American publicly traded airline holding company headquartered in Fort Worth, Texas. It was formed on December 9, 2013, by the merger of AMR Corporation, the parent company of American Airlines, and US Airways Group, the parent company of US Airways. Integration was completed when the Federal Aviation Administration granted a single operating certificate for both carriers on April 8, 2015, and all flights now operate under the American Airlines brand. The group operates the largest airline in the world, as measured by number of passengers carried, by fleet size and by scheduled passenger-kilometers flown. The company ranked No. 70 in the Fortune 500 list of the largest United States corporations based on its 2019 revenue, but, impacted by the COVID-19 pandemic, it lost $2.2 billion in the first quarter of 2020 alone and accepted government aid. American Airlines is reported to be shrinking its passenger fleet.

Information about this dataset

This dataset provides historical data of American Airlines Group Inc. (AAL). The data is available at a daily level. Currency is USD.

The Reporting Carrier On-Time Performance Dataset contains information on approximately 200 million domestic US flights reported to the United States Bureau of Transportation Statistics. The dataset contains basic information about 2 million flights (such as date, time, departure airport, arrival airport) and, if applicable, the amount of time the flight was delayed and information about the reason for the delay. This dataset can be used to predict the likelihood of a flight arriving on time.

What is Data Expo 2009 - Airline on-time performance?

Have you ever been stuck in an airport because your flight was delayed or canceled and wondered if you could have predicted it if you'd had more data? This is your chance to find out.

.

How to use this dataset

We had a total of nine entries, and turn ou at the poster session at the JSM was great, with plenty of people stopping by to find out why their flights were delayed.

Acknowledgments

When we use this dataset in our research, we credit the authors.

• License : CC BY 4.0.

• This data set is taken from Harvard Dataset- Data Expo 2009: Airline on time data

The main idea for uploading this dataset is to practice data analysis with my students, as I am working in college and want my student to train our studying ideas in a big dataset, It may be not up to date and I mention the collecting years, but it is a good resource of data to practice

For most American Airlines service requests, the processing time over the phone varies between 5 minutes and 72 hours, depending on complexity, volume, and staffing availability. ☎️+1 (855) 217-1878 For simpler matters like seat selection or same-day change requests, agents can usually resolve things within minutes. ☎️+1 (855) 217-1878

If you’re calling to cancel a flight, reschedule, request a refund, or apply travel credits, the process often takes 15–30 minutes depending on your itinerary and status. ☎️+1 (855) 217-1878 Elite status members typically experience shorter wait times due to priority lines. ☎️+1 (855) 217-1878 However, during peak travel seasons, even elite flyers may face longer processing delays.

Complex changes like multi-city itinerary updates or flight disruptions caused by weather may require manual review by a supervisor, which can extend processing times to several hours. ☎️+1 (855) 217-1878 American Airlines support agents may need to consult backend systems, fare codes, or airline partners in such cases. ☎️+1 (855) 217-1878 These requests are often queued internally for approval.

During periods of high call volume—such as holidays or major travel disruptions—wait times to speak with a live agent can exceed 90 minutes. ☎️+1 (855) 217-1878 If your call involves a time-sensitive issue, use the “Call Back” option when available to hold your place in line. ☎️+1 (855) 217-1878 This saves time and reduces stress.

In cases where your call includes rebooking due to cancellations initiated by American Airlines, agents may prioritize your request and finish processing in under 30 minutes. ☎️+1 (855) 217-1878 Since airline-initiated changes are not your fault, the support team works quickly to find alternate flights or refunds. ☎️+1 (855) 217-1878 Document your case number for easy follow-up.

It’s also important to note that some changes don’t go into effect immediately, even after a successful phone call. For example, flight credit applications may show a delay of 24–48 hours on your American account. ☎️+1 (855) 217-1878 That doesn’t mean your request failed—it simply reflects backend processing time. ☎️+1 (855) 217-1878 Check your email for confirmation and save it.

Refund requests placed by phone are usually processed within 10 minutes on the call, but they are marked as “pending” until finance confirms the refund action. ☎️+1 (855) 217-1878 This phase can take a bit longer, as we’ll discuss in the next section about refund timelines. ☎️+1 (855) 217-1878 Phone agents cannot expedite payment disbursement.

If your phone request involves AAdvantage mileage adjustments or missing miles claims, processing takes longer—sometimes 5–10 business days depending on the route and booking platform. ☎️+1 (855) 217-1878 This is because partner airline data must sync with American’s systems before adjustments are completed. ☎️+1 (855) 217-1878 Screenshot your ticket for proof when requesting mileage corrections.

To speed up any phone-based service, have your 6-digit record locator, frequent flyer number, and credit card (if needed) ready before calling. ☎️+1 (855) 217-1878 Clear communication, patience, and politeness help agents complete your request quickly. ☎️+1 (855) 217-1878 Take notes during the call in case you need to follow up.

If something goes wrong during the call or you're disconnected, don’t worry. American logs most requests in their system, and any changes already made ☎️+1 (855) 217-1878 will remain in place even if the call doesn’t complete fully. Just call back with your reference number. ☎️+1 (855) 217-1878 The next agent can pick up where things left off.

Have you ever been stuck in an airport because your flight was delayed or cancelled and wondered if you could have predicted it if you'd had more data? This is your chance to find out.

The 2009 ASA Statistical Computing and Graphics Data Expo consisted of flight arrival and departure details for all commercial flights on major carriers within the USA, from October 1987 to April 2008. This is a large dataset containing nearly 120 million records in total.

The aim of the data expo is to provide a graphical summary of important features of the data set. This is intentionally vague in order to allow different entries to focus on different aspects of the data, but here are a few ideas to get you started: •When is the best time of day, day of the week, and time of year to fly to minimise delays? •Do older planes suffer more delays? •How well does weather predict plane delays? •How does the number of people flying between different locations change over time? •Can you detect cascading failures as delays in one airport create delays in others? Are there critical links in the system? •Use the available variables to construct a model that predicts delays.
