The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today that U.S. airlines’ systemwide (domestic and international) scheduled service load factor – a measure of the use of airline capacity – fell to 83.5 percent in March, seasonally-adjusted, declining after rising for three consecutive months (Table 1). Seasonal adjustment allows the comparing of monthly load factors to all other months.

Load Factor on All U.S. Scheduled Airlines (Domestic & International),
March 2010 - March 2015

Table Version | Excel

Load Factor on All U.S. Scheduled Airlines (Domestic & International), March 2010 - March 2015

U.S. airlines reported a seasonally-adjusted all-time monthly high of systemwide passenger enplanements in March of 65.0 million, exceeding the previous record in August 2007 by 0.3 percent (Table 8). They also reported a seasonally-adjusted all-time monthly high of systemwide Revenue Passenger-Miles (RPMs) in March of 73.5 billion, exceeding the previous record in December 2014 by 0.2 percent (Table 4). These all-time highs did not result in a higher load factor in March because of the growth in airline capacity.

The March load factor of 83.5 was below the all-time seasonally-adjusted high of 84.6 reached in January 2014 and was the eighth highest all-time (Table 2). Load factor is a measure of the use of aircraft capacity that compares the system use, measured in RPMs as a proportion of system capacity, measured in Available Seat-Miles (ASMs).

The seasonally-adjusted load factor fell in March following a rise in February to 84.0, the highest point in 12 months (Table 1). The load factor declined from February to March despite a 0.7 percent increase in RPMs because system capacity grew faster (1.3 percent increase in ASMs) (Tables 3, 5).

BTS is replacing previous monthly Air Traffic press releases with this monthly press release using seasonally-adjusted data. Tables 2, 8 and 14 of the previous press release can be found at the end of the Unadjusted section of this press release. Additional traffic data can be found on the BTS Airlines and Airports page.

Trends:

Seasonally-adjusted
The March load factor (83.5) continued the trend to higher load factors as all of the top 10 load factor months have been post-recession. February 2015 was the third highest month all-time and March was the eighth (Table 2). Load factors have generally increased since the recession because passenger travel has increased at a faster pace than capacity. In March, RPMs, the passenger measure used to calculate load factor, reached the highest all-time level. However, the RPM increase did not keep pace with the increase in ASMs, leading to a decrease in the load factor. The last nine months, starting with July 2014 through March 2015 are the nine all-time highest months for RPMs (Table 4).

Seasonally-adjusted trends are for the time period January 2000 to present.

Unadjusted
Systemwide: Load factor (83.9) was up from March 2014 but down from the all-time March high set in 2013 (84.3). The number of passengers, RPMs and ASMs reached all-time highs for the month of March.

For the first quarter, January through March, load factor (81.2) was down from the all-time March high set in 2014 (81.3). RPMs reached an all-time high for the first quarter, exceeding the previous high set in 2008. The number of passengers and ASMs were below the 2008 levels.

Domestic: Load factor (85.8) was at an all-time high for the month of March, exceeding the previous high set in 2014 (85.5). The number of passengers and RPMs reached all-time highs for the month of March. ASMs remained below the pre-recession levels.

International: Load factor (79.5), while up from March 2014, was below the all-time March high set in 2013 (82.5). The number of passengers was down 0.4 percent from the all-time highs for the month of March, set in 2014. RPMs and ASMs were virtually unchanged from all-time highs set in March 2014.

Unadjusted trends are for the time period January 1996 to present. Unadjusted data are available at Customize Table and can be downloaded from the seasonally-adjusted data  page.

Seasonally-Adjusted Air Travel

Seasonally-Adjusted Revenue Passenger-Miles

RPMs rose 0.7 percent from February to March, the second consecutive month of growth (Table 3).

RPMs of 73.5 billion in March were the highest all-time seasonally-adjusted total. Three of the top 10 all-time highest months for RPMs have been in 2015 and seven were in 2014 (Table 4).

Seasonally-Adjusted Available Seat-Miles

ASMs rose 1.3 percent from February to March following two consecutive months of decline (Table 5).

ASMs of 88.0 billion in March were the fifth highest all-time seasonally-adjusted total, 0.3 billion or 0.4 percent less than the all-time seasonally-adjusted high reached in November 2007. Two of the top 10 all-time highest months for ASMs have been in 2015 and two were in 2014 (Table 6).

Seasonally-Adjusted Passenger Enplanements

Systemwide: Systemwide passenger enplanements rose 0.8 percent from February to March, Increasing after a decline from January to February that followed seven consecutive months of growth (Table 7). The systemwide total rose from February to March because of growth in domestic enplanements (0.9 percent). The systemwide increase took place despite a 0.8 percent decline in international enplanements (Tables 9, 11).

Enplanements of 65.0 million in March were the highest all-time seasonally-adjusted total. Three of the top 10 all-time highest months for enplanements have been in 2015 and one in 2014 (Table 8).

Domestic: Enplanements on domestic flights rose 0.9 percent from February to March, reaching the highest level since the recession (Table 9). Domestic enplanements in March (56.7 million) were the eighth highest all-time seasonally-adjusted total, 1.0 percent less than the all-time seasonally-adjusted high in August 2007 (57.2 million). March is the first post-recession month among the top 10 all-time highest months for domestic enplanements (Table 10).

International: U.S. airlines’ international enplanements fell 0.1 percent from February to March for the third consecutive monthly decline. The March level (8.35 million) was the ninth highest all-time seasonally-adjusted total, 0.5 percent less than the all-time seasonally-adjusted high in December 2014 (8.40 million). Three of the top 10 all-time highest months for international enplanements have been in 2015 and seven were in 2014 (Tables 11, 12). 

Unadjusted Tables

Unadjusted Load Factor
U.S. airlines’ systemwide (domestic and international) scheduled service load factor was 83.9 percent in March, up from February (80.2) and up from March 2014 (83.5) (Table 13).

The March load factor of 83.9 was down from the all-time unadjusted high for the month of March of 84.3 reached in 2013. The March load factor was below the all-time unadjusted high of 87.0 in June 2013 (Table 14).

The load factor rose year-over-year as a result of a 2.9 percent increase in RPMs from March 2014 to March 2015 combined with a 2.4 percent increase in ASMs (Tables 15, 17).

Unadjusted Revenue Passenger-Miles

RPMs in March increased 26.7 percent from February and increased 2.9 percent from March 2014 (Table 15).

RPMs of 75.7 billion in March were 9.5 percent less than the all-time unadjusted high reached in July 2014. All of the top 10 all-time highest months for RPMs have been summer months, including the three summer months in 2014 (Table 16).

Unadjusted Available Seat-Miles

ASMs in March increased 21.1 percent from February and increased 2.4 percent from March 2014 (Table 17).

ASMs of 90.3 billion in March were 6.4 percent less than the all-time unadjusted high reached in July 2014. All of the top 10 all-time highest months for ASMs have been summer months, including the three summer months in 2014 (Table 18).

Unadjusted Passenger Enplanements

Systemwide: Systemwide unadjusted passenger enplanements in March 2015 (68.1 million) rose 25.8 percent from February and 2.6 percent from March 2014 (Table 19).

The March 2015 systemwide enplanement total (68.1 million) was 5.9 percent less than the all-time unadjusted high reached in July 2007 (72.4 million). The March 2015 level was the all-time unadjusted high for the month of March although it was below the all-time unadjusted highs (Table 20).

Domestic: Domestic unadjusted passenger enplanements in March 2015 (59.5 million) rose 26.2 percent from February and rose 3.0 percent from March 2014 (Table 21).

The March 2015 domestic enplanement total (59.5 million) was 6.2 percent less than the all-time unadjusted high reached in July 2007 (63.5 million). The March 2015 level was the all-time unadjusted high for the month of March although it was below the all-time unadjusted highs (Table 22).

International: International unadjusted passenger enplanements in March 2015 (8.6 million) rose 23.6 percent from February but fell 0.4 percent from March 2014 (Table 23).

The March 2015 international enplanement total (8.6 million) was 14.7 percent less than the all-time unadjusted high reached in July 2014 (10.1 million). The March 2015 level was down 0.4 percent from the all-time unadjusted high for the month of March (8.7 million) reached in 2014 (Table 24).

Explanation of seasonal adjustment
When the primary purpose is to examine monthly shifts in transportation services output and analyze short-term trends, the variation introduced by normal seasonal changes must be removed from the data. Transportation is highly seasonal, and without adjustment, the data do not give an accurate picture of underlying changes in aviation, passenger travel.

Seasonal adjustment of the data removes the seasonal events that follow a regular seasonal pattern. Changes that are not due to seasonality, such as a change in air travel resulting from economic conditions become more readily apparent.

The aviation data are seasonally-adjusted for the effects of trading day, moving holidays, and data outliers.

See Seasonal Adjustment for methodology and additional explanation.
