September 2015 U.S. Airline Traffic Data
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 rose to 84.1 percent in September, seasonally adjusted, following a one month decline (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),
September 2010 - September 2015
The September load factor of 84.1, up from 83.6 in August (Table 1), was below the all-time seasonally-adjusted high of 84.5 in January 2014 (Table 2). Load factor is a measure of the use of aircraft capacity that compares the system use, measured in Revenue Passenger-Miles (RPMs) as a proportion of system capacity, measured in Available Seat-Miles (ASMs).
The load factor rose month-to-month because of a combined increase in passenger travel (RPMs rose from August to September) and decline in capacity (Tables 3, 4, 5).
Trends:
Seasonally-adjusted
September was the seventh consecutive month in which passenger enplanements reached a seasonally-adjusted all-time high (Table 8). RPMs rose 0.4 percent from August but were down 0.2 percent from the all-time high in July (Table 4). Capacity was down 0.2 percent from the all-time high in August (Table 6). The September load factor (84.1) was the fourth highest all-time (Table 2).
Seasonally adjusted trends are for the time period January 2000 to present.
Unadjusted
Systemwide: September load factor (83.0) was the highest for the month of September, up from the previous September high set in 2014 (81.9) (Table 13). The number of passengers, RPMs and ASMs all reached record highs for any September.
Domestic: September load factor (83.8) was the highest for the month of September, up from the previous September high set in 2014 (82.1). The number of passengers and RPMs reached record highs for any September. ASMs were below the September 2007 level.
International: September load factor (81.4) was down from the all-time September high set in 2010 (83.6). The number of passengers, RPMs and ASMs all reached record highs for any September.
For the first nine months of 2015, January through September, systemwide load factor (83.9) equaled the all-time high set in 2014 (83.9). The number of systemwide passengers, RPMs and ASMs all reached record highs for the first nine months of any year.
Unadjusted trends are for the time period January 1996 to present. 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 0.4 percent from August to September following a single month of decline from July to August (Table 3).
RPMs of 76.2 billion in September were the second all-time highest seasonally-adjusted total, 150 million or 0.2 percent less than the all-time seasonally-adjusted high reached in July 2015. Nine of the top 10 all-time highest months for RPMs have been in 2015 and one was in 2014 (Table 4).
Seasonally-Adjusted Available Seat-Miles
ASMs fell 0.2 percent from August to September following six months of growth from February to August (Table 5).
ASMs of 90.6 billion in September were the third all-time highest seasonally-adjusted total, 138 million or 0.2 percent less than the all-time seasonally-adjusted high reached in August 2015. Seven of the top 10 all-time highest months for ASMs have been in 2015 and one was in 2014 (Table 6).
Seasonally-Adjusted Passenger Enplanements
Systemwide: Systemwide passenger enplanements rose 0.4 percent from August to September, the seventh consecutive month of growth (Table 7). The systemwide total rose from August to September despite a 0.3 percent decline in international enplanements because of growth in domestic enplanements (0.4 percent) (Tables 9, 11).
Enplanements of 67.6 million in September were the all-time highest seasonally-adjusted total. Eight of the top 10 all-time highest months for systemwide enplanements have been in 2015 (Table 8).
Domestic: Enplanements on domestic flights rose 0.4 percent from August to September, the 13th consecutive month of growth (Table 9). Domestic enplanements in September (58.9 million) were the highest all-time seasonally-adjusted total. Seven of the top 10 all-time highest months for domestic enplanements have been in 2015 (Table 9, 10).
International: U.S. airlines’ international enplanements fell 0.3 percent from August to September. International enplanements were virtually unchanged from July to August after rising for five consecutive months. The September level (8.6 million) was the third highest all-time seasonally-adjusted total, 0.3 percent less than the all-time seasonally adjusted high reached in July 2015 (8.6 million). Seven of the top 10 all-time highest months for international enplanements have been in 2015 and three were in 2014 (Tables 11, 12).
Unadjusted Tables
Unadjusted Load Factor
U.S. airlines’ systemwide (domestic and international) scheduled service load factor – a measure of the use of airline capacity – was 83.0 percent in September, down from August and up from September 2014 (Table 13).
The September load factor of 83.0 was up from the all-time unadjusted high for the month of September (81.9) reached in 2014 (Table 13).
The load factor rose year-to-year because passenger travel grew faster (6.2 percent increase in RPMs) than system capacity (4.8 percent increase in ASMs) (Tables 15, 17).
Unadjusted Revenue Passenger-Miles
RPMs in September declined 14.8 percent from August but increased 6.2 percent from September 2014 (Table 15).
RPMs of 72.6 billion in September were 17.7 percent less than the all-time unadjusted high reached in July 2015. Three of the top 10 all-time highest months for RPMs have been in 2015 and three were in 2014 (Table 16).
Unadjusted Available Seat-Miles
ASMs in September declined 11.3 percent from August but increased 4.8 percent from September 2014 (Table 17).
ASMs of 87.5 billion in September were 13.4 percent less than the all-time unadjusted high reached in July 2015. Four of the top 10 all-time highest months for ASMs have been in 2015 and two were in 2014 (Table 18).
Unadjusted Passenger Enplanements
Systemwide: Systemwide unadjusted passenger enplanements in September 2015 (63.9 million) fell 12.3 percent from August and rose 6.5 percent from September 2014 (60.0 million) (Table 19).
The September 2015 systemwide enplanement total (63.9 million) was 15.5 percent less than the all-time unadjusted high reached in July 2015 (75.6 million). The September 2015 level was the all-time unadjusted high for any September (Table 20).
Domestic: Domestic unadjusted passenger enplanements in September 2015 (56.2 million) fell 10.5 percent from August and rose 6.9 percent from September 2014 (52.5 million) (Table 21).
Domestic unadjusted passenger enplanements in September 2015 (56.2 million) were 13.8 percent less than the all-time unadjusted high reached in July 2015 (65.1 million). The September 2015 level was the all-time unadjusted high for the month of September (Table 22).
International: International unadjusted passenger enplanements in September 2015 (7.8 million) fell 23.2 percent from August and rose 3.9 percent from September 2014 (7.5 million) (Table 23).
International unadjusted passenger enplanements in September 2015 (7.8 million) were 26.2 percent less than the all-time unadjusted high reached in July 2015 (10.5 million). The September 2015 level was the all-time unadjusted high for the month of September (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.
