Global airlines' combined passenger load factor has been gradually trending upward over the last 15 years; from 75.2 percent in 2005 to 82.6 percent in 2019. In 2020, due to the coronavirus pandemic, passenger load factor dropped to 65 percent. However, it rebounded and forecast to reach 82,5 percent in 2024.
Passenger load factor Passenger load factor (PLF) is a measure of how much of an airline’s passenger carrying capacity has been utilized. It is calculated by dividing the revenue passenger kilometers, which is the total number of kilometers flown by passengers, by the available seat kilometers, which is the total number of kilometers flown for every seat in an aircraft (regardless of whether it has been filled or not). A higher passenger load factor therefore means that there are less empty seats on each aircraft, but does not indicate anything about changes in the total number of kilometers flown per passenger or per seat . PLF and profitability As airlines have fixed costs associated with every flight, a higher PLF will generally mean a higher profit margin for airlines. PLF is only one factor affecting total profitability though, meaning increases in PLF do not necessarily correspond with higher profits. In particular, the cost of airline fuel, which can be highly variable, has a strong effect on the operating margin of airlines. This can be seen clearly in through the jump in profitability from 2014 to 2015, which corresponds with a steep drop in the expenditure required for fuel.

Due to the coronavirus outbreak worldwide, airlines in the Asia Pacific region had an international passenger load factor of **** percent in December 2021, up from **** percent registered in the previous month. For further information about the coronavirus (COVID-19) pandemic, please visit our dedicated Fact and Figures page. Passenger load factor When it comes to international passenger boardings, John F. Kennedy International Airport in New York (JFK) is the busiest airport in the United States, its most in-demand transatlantic route being the passage to London Heathrow (LHR). Aircraft that are used on flight routes with a very high passenger demand require a high seating capacity to transport as many passengers as possible on board. The full utilization of an aircraft’s seating capacity is an effective measurement for airlines to increase revenue. To give an example, the largest Dreamliner variant seats up to *** passengers, and the flight distance from John F. Kennedy airport to >London Heathrow comes to around ***** miles. The passenger load factor is the quotient of the number of seat miles and passenger miles traveled. While seat miles are calculated by multiplying the number of seats on board with the number of miles travelled, passenger miles are the product of the amount of miles traveled and the number of passengers carried. A fully-seated Dreamliner traveling from JFK to LHR carries the same number of seat and passenger miles and thus has a passenger load factor of one. In other words, its seating capacity is fully utilized.

This paper examines the permanence of excess capacity in the US airline industry. To avoid the problems with the standard engineering measure of capacity utilization, load factor, we define and measure capacity as an economic concept. Two measures of economic capacity utilization are then computed one, a demand-based measure and the other an output-based measure of capacity utilization. Both measures share little in common with the standard engineering measure (load factor) and reveal some interesting attributes of airline travel demand. This paper also provides interesting new insights into the role of deregulation and the costs of excess capacity during regulation. Specifically, it is found that deregulation with the concomitant rationalization of route structures enabled airlines to move closer to their optimal levels of capacity and facilitated substantial improvements in capacity utilization and cost reductions over the period considered.

For calculating the GLOWOPT representative route network, a forecast model chain was used. The model was calibrated with 2019 flight movement data (unimpeded by COVID-19) and provided forecasted aircraft movements from the year 2019 (~2020) to 2050 in 5 years intervals.

Two formats of datasets are generated with the results of the forecast model chain, a csv file format and 4-dimensional array supported with MATLAB (.mat).

CSV Datasets

For each forecasted year a csv file is generated with the information on the origin-destination (OD) airports IATA codes, region, latitude and longitude of OD pair, representative aircraft type along with the aircraft category , the average load factor and finally, the distance between the OD pair. The airports worldwide are sub-dived into nine regions namely Africa, Asia, Caribbean, Central America, Europe, Middle East, North America, Oceania and South America. There are total of seven datasets, one for each forecasted year i.e. for years 2019 (~2020), 2025, 2030, 2035, 2040, 2045 and 2050.

Description of the data labels:

Origin- Origin airport IATA code

Origin_Region- Region of the Origin Airport

Origin_Latitude- Latitude of the Origin Airport

Origin_Longitude- Longitude of the Origin Airport

Destination- Destination airport IATA code

Destination_Region- Region of the Destination Airport

Destination_Latitude- Latitude of the Destination Airport

Destination_Longitude- Longitude of the Destination Airport

AcType- Representative aircraft type

Load_Factor- Average load factor per flight

Yearly_Frequency- Total aircraft movements per annum

RefACType- Aircraft Category based on number of seats (Category 6 represents aircraft with seats 252-301 and category 7 represents aircraft with seats greater than 302.)

Distance- Great circle distance between Origin and Destination in Km.

MATLAB Datasets

The dataset generated with MATLAB is a 4-dimensional array with the extension *.mat. The first dimension is the region of the origin airport and subsequently the second dimensions contains the region of the destination airport. The third and fourth dimension are the aircraft category based on seat numbers and the categorized great circle distances. The information received therein is a 1X1 cell with the IATA codes of the OD pairs, frequency and great circle distance in Km.

The 4D array is categorised such that the user can select the route segment specific to a region or a combination of regions. The range categorisation in combination with an aircraft category additionally offers the user the possibility to select routes depending on their great circle distances. The ranges are categorised to represent very short range (0-2000 km), short range (2000-6000 km), medium range (6000-10000 km) and long range (10000 – 15000 km).
