Passengers enplaned and deplaned at Canadian airports, annual.
Over 50 million American Airlines passengers book tickets annually, and many opt for Basic Economy due to its affordability. However, the low price comes with strict rules. ☎️+1 (855) 217-1878 One of the most limiting restrictions is the ability to change the flight, especially once the 24-hour grace period has expired. ☎️+1 (855) 217-1878
American Airlines’ Basic Economy fare is designed for ultra-budget travelers who are confident in their plans. These fares offer lower prices but minimal flexibility. ☎️+1 (855) 217-1878 Most Basic Economy tickets cannot be changed or modified once purchased, and that includes changes to dates, times, or destinations. ☎️+1 (855) 217-1878 No upgrades or rerouting is allowed after the 24-hour cancellation window closes.
If your Basic Economy flight was booked less than 24 hours ago and the departure is two or more days away, you are eligible for a free cancellation. ☎️+1 (855) 217-1878 This U.S. Department of Transportation rule allows a full refund or itinerary change within that timeframe. ☎️+1 (855) 217-1878 Once that 24-hour window passes, changes are generally not permitted.
Many travelers are surprised to find out that Basic Economy doesn't allow for even same-day changes or standby options, unlike other fare classes. ☎️+1 (855) 217-1878 So, if you're hoping to hop on an earlier flight, that option simply isn’t available for Basic Economy. ☎️+1 (855) 217-1878 These tickets are non-flexible by design.
The policy may seem harsh, but it's clear. When you purchase Basic Economy, you're entering an agreement that limits flexibility in exchange for a lower price. ☎️+1 (855) 217-1878 American Airlines provides detailed warnings during booking to ensure customers understand this. ☎️+1 (855) 217-1878 The restrictions are also listed in the fare rules on your email confirmation.
There are rare exceptions. For instance, if the airline cancels or significantly changes your itinerary—usually a delay of over 60 minutes—you may qualify for a rebooking. ☎️+1 (855) 217-1878 In these instances, American may waive the no-change rule due to operational issues beyond your control. ☎️+1 (855) 217-1878 Still, these exceptions are granted at American’s discretion.
Another edge case involves waivers during events like hurricanes, political unrest, or global pandemics. American sometimes issues travel waivers that temporarily lift restrictions for Basic Economy passengers. ☎️+1 (855) 217-1878 You must call customer service to take advantage of these opportunities—online platforms usually won’t permit Basic Economy changes. ☎️+1 (855) 217-1878 Act quickly when a waiver is announced.
Many travelers wonder if they can just pay a fee to change their Basic Economy ticket. The short answer is no. ☎️+1 (855) 217-1878 Unlike Main Cabin or Business Class, there’s no fee-based option to modify Basic Economy—it’s either eligible for cancellation under DOT rules or completely locked in. ☎️+1 (855) 217-1878
If you suspect your travel plans may change, it’s wise to avoid booking Basic Economy in the first place. Even a slightly more expensive Main Cabin fare offers flexibility. ☎️+1 (855) 217-1878 With Main Cabin, you can cancel, change, or reschedule with or without a fee depending on the route. ☎️+1 (855) 217-1878 That freedom is worth the cost for many.
Ultimately, the inability to change Basic Economy flights is a deliberate tradeoff. You get a cheaper ticket but lose the ability to pivot later. ☎️+1 (855) 217-1878 For those with fixed schedules, this is fine—but for anyone with uncertain plans, it’s risky. ☎️+1 (855) 217-1878 Always read fare terms and understand what you’re buying.
To summarize: unless you’re still within the 24-hour cancellation window or there's a special waiver or major schedule disruption, you cannot change a Basic Economy ticket. ☎️+1 (855) 217-1878 If you're unsure whether your situation qualifies, speak to an American Airlines representative directly. ☎️+1 (855) 217-1878 They can clarify your options based on current policies and your booking.
Over 90% of American Airlines passengers eventually need to change or cancel a booking at some point. The quickest and most effective way to handle this is by calling ☎️+1 (855) 217-1878. While the airline offers online tools, not all itineraries are eligible for self-service. ☎️+1 (855) 217-1878 Speaking directly with a trained representative helps speed up solutions for more complex issues.
The first step in getting fast help is to prepare your details in advance. This includes your six-character record locator, full name as on the ticket, and your travel dates. ☎️+1 (855) 217-1878 Having your AAdvantage frequent flyer number ready can also accelerate verification. ☎️+1 (855) 217-1878 Make sure to call during non-peak hours (late evenings or early mornings) to reduce hold time.
American Airlines customer service receives thousands of calls per day, especially during holidays, storm seasons, or global disruptions. That’s why it’s often faster to use their dedicated change and cancellation line ☎️+1 (855) 217-1878 rather than the general customer service number. ☎️+1 (855) 217-1878 Representatives on this line are specially trained in fare flexibility and ticket policies.
When you call, be clear about the reason for your request. If you're canceling due to personal reasons, American may offer you a credit, refund, or rescheduling options. ☎️+1 (855) 217-1878 If the airline has canceled your flight or changed your schedule, you may be entitled to a full refund. ☎️+1 (855) 217-1878 Knowing your rights helps you get faster and better service.
Refundable tickets are much easier to cancel with minimal effort. With a refundable fare, you can cancel or rebook directly over the phone in under 15 minutes. ☎️+1 (855) 217-1878 The refund is processed automatically and sent back to your original form of payment. ☎️+1 (855) 217-1878 The same applies to flights changed within 24 hours of booking.
For non-refundable tickets, phone agents can still help, especially if a waiver or special circumstance applies. If you or an immediate family member experiences an emergency, ☎️+1 (855) 217-1878 American may allow cancellations with minimal penalty or convert your booking into flight credit. ☎️+1 (855) 217-1878 Always ask what accommodations exist based on your situation.
The “Trip Credit” system allows you to reuse the value of a canceled ticket. You can request this over the phone and receive a confirmation within 24 to 48 hours. ☎️+1 (855) 217-1878 The agent will email you a code to use for future flights. ☎️+1 (855) 217-1878 These credits are typically valid for 12 months from the original booking date.
Another tip: Be kind and respectful to the phone agent. Support reps are more willing to go the extra mile when callers are polite and prepared. ☎️+1 (855) 217-1878 This could mean waiving fees or offering better flight alternatives. ☎️+1 (855) 217-1878 Jot down the agent’s name and your case number for tracking purposes.
Always double-check your confirmation email after a change or cancellation. If you notice a mistake, call back immediately—most corrections can be fixed without penalty within 24 hours. ☎️+1 (855) 217-1878 This prevents future issues during check-in or boarding. ☎️+1 (855) 217-1878 Your updated itinerary should reflect any adjustments made during your call.
If you're unable to reach customer service due to high call volume, consider using the chat feature on the American Airlines mobile app. In many cases, you’ll be directed ☎️+1 (855) 217-1878 to someone who can resolve your issue faster. It works well for simple requests and cancellations. ☎️+1 (855) 217-1878 But for complex changes, stick with the phone.

Generally, fare holds last between 24 and 72 hours. 📞+1 (844) 459-5676 You’re given explicit deadlines and confirmation codes. 📞+1 (844) 459-5676
During the hold, you can secure everything—seat choice, service class, ancillary add-ons—while awaiting visa approval or funds. 📞+1 (844) 459-5676 It ensures pricing won’t increase with airline fluctuations. 📞+1 (844) 459-5676
If fancying a group trip or corporate meeting, agents can create provisional group blocks and hold space pending final attendance confirmation. 📞+1 (844) 459-5676 These holds accommodate school trips and conferences. 📞+1 (844) 459-5676
When holding for visa purposes, request a “temporary itinerary” via phone. 📞+1 (844) 459-5676 The agent issues a PNR and documentation recognized by consulates and embassies worldwide. 📞+1 (844) 459-5676
This temporary itinerary isn’t ticketed yet but shows flight details and placeholder pricing—ideal for visa submissions. 📞+1 (844) 459-5676 Hold expires if not ticketed. 📞+1 (844) 459-5676
If circumstances change, you can return to Lufthansa with updated plans before the hold expires. 📞+1 (844) 459-5676 If the fare is gone, you might need a new option. 📞+1 (844) 459-5676
Some third-party travel agencies and visa consultants also offer hold services, but these often incur extra fees. 📞+1 (844) 459-5676 Booking via Lufthansa directly is usually more cost-effective. 📞+1 (844) 459-5676
Keep in mind not all fares or routes qualify for a hold. 📞+1 (844) 459-5676 Budget Basic fares are frequently excluded. 📞+1 (844) 459-5676
If hold isn’t available, agents might provide an alternative—like a refundable booking or guidance for flexible policies. 📞+1 (844) 459-5676 Always ask about flexibility and refund windows. 📞+1 (844) 459-5676
Remember that after the hold ends, you must confirm the booking and complete payment. 📞+1 (844) 459-5676 If not, the system releases the seat automatically. 📞+1 (844) 459-5676
To activate the hold, you may need to share basic ID or customer info for verification. 📞+1 (844) 459-5676 It enhances booking accuracy. 📞+1 (844) 459-5676
One significant advantage of holding flights is locking in promotions temporarily. 📞+1 (844) 459-5676 This avoids losing deals while sorting logistics. 📞+1 (844) 459-5676
Another method is through Lufthansa’s “flexible ticket” options. 📞+1 (844) 459-5676 These allow free cancellations within 24 hours of purchase without completion. 📞+1 (844) 459-5676
However, flexible fares require immediate ticketing—even if refundable—and aren’t the same as fee-less holds. 📞+1 (844) 459-5676 Evaluate needs carefully. 📞+1 (844) 459-5676
Frequent flyer members may enjoy more hold privileges based on membership tier. 📞+1 (844) 459-5676 Higher tiers might waive hold fees entirely. 📞+1 (844) 459-5676
If needing help—such as emergency travel—or facing complex group bookings, hold service can be crucial. 📞+1 (844) 459-5676 Agents can coordinate with other Lufthansa teams if needed. 📞+1 (844) 459-5676
To avoid losing the hold, jot down the hold expiration date and time given by the agent. 📞+1 (844) 459-5676 Set a reminder to complete payment before the deadline. 📞+1 (844) 459-5676
In summary, yes—you can normally reserve a Lufthansa flight without immediate payment via fare hold, fare lock, or provisional itinerary. 📞+1 (844) 459-5676 Just call, confirm the hold for your itinerary, and follow up. 📞+1 (844) 459-5676

Overview:
This repository contains the raw images for the dataset of Thermal Bridges on Building Rooftops (TBBR) dataset.
This dataset contains 5696 drone images (2848 RGB and 2848 thermal) of building rooftops, recorded with a normal (RGB) and a FLIR-XT2 (thermal) camera on a DJI M600 drone. They show six large building blocks of around 20 buildings per block recorded in the city centre of the German city Karlsruhe east of the market square. Because of a high overlap rate of the images, the same buildings are on average recorded from different angles in different images about 20 times.
All images were recorded during a drone flight on March 19, 2019 from 7 a.m. to 8 a.m. At this time, temperatures were between 3.78 ° C and 4.97 ° C, humidity between 80% and 98%. There was no rain on the day of the flight, but there was 2.3mm/m² 48 hours beforehand. For recording the thermographic images an emissivity of 1.0 was set. The global radiation during this period was between 38.59 W / m² and 120.86 W / m². No direct sunlight can be seen visually on any of the recordings.
Usage:
Each zip archive file represents one of the six drone flight paths. The archives contain JPG files of size 4000x3000 pixels (RGB) and 640x512 (Thermal), separated into individual directories for RGB and Thermal:
├── Flug_100/
│ ├── RGB/
│ │ ├── DJI_0004.jpg
│ │ ├── DJI_0006.jpg
│ │ └── ...
│ └── Thermal/

│ │ └── ...
│ └── Thermal/
│ ├── DJI_0000_R.JPG
│ ├── DJI_0002_R.JPG
│ └── ...
└── ...
File Numbering/Naming Scheme:
The pairs of RGB + Thermal images follow the simple numbering scheme of: RGB = Thermal + 1.
For example, DJI_0003_R.jpg and DJI_0004.JPG are the matching Thermal and RGB images, respectively, that can be merged to form a single hyperspectral drone image.
To perform the merging, we recommend using the merge_image_layers.py script provided by the associated TBBRDet software (see the scripts/alignment/ directory).
For convenience, we have provided a CSV listing all annotated images in the Thermal Bridges on Building Rooftops (TBBR) dataset. The CSV format is as follows:
Flight,RGB,Thermal
Flug_100,DJI_0048.jpg,DJI_0047_R.JPG
Flug_100,DJI_0050.jpg,DJI_0049_R.JPG

As a result of the continued annual growth in global air traffic passenger demand, the number of airplanes that were involved in accidents is on the increase. Although the United States is ranked among the 20 countries with the highest quality of air infrastructure, the U.S. reports the highest number of civil airliner accidents worldwide. 2020 was the year with more plane crashes victims, despite fewer flights The number of people killed in accidents involving large commercial aircraft has risen globally in 2020, even though the number of commercial flights performed last year dropped by 57 percent to 16.4 million. More than half of the total number of deaths were recorded in January 2020, when an Ukrainian plane was shot down in Iranian airspace, a tragedy that killed 176 people. The second fatal incident took place in May, when a Pakistani airliner crashed, killing 97 people. Changes in aviation safety In terms of fatal accidents, it seems that aviation safety experienced some decline on a couple of parameters. For example, there were 0.37 jet hull losses per one million flights in 2016. In 2017, passenger flights recorded the safest year in world history, with only 0.11 jet hull losses per one million flights. In 2020, the region with the highest hull loss rate was the Commonwealth of Independent States. These figures do not take into account accidents involving military, training, private, cargo and helicopter flights.
