August 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 – a measure of the use of airline capacity – fell to 83.5 percent in August, seasonally adjusted, following three consecutive months of growth (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),
August 2010 - August 2015
The August load factor of 83.5 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 seasonally-adjusted load factor fell in August following a rise in July to 84.1, the highest point in 12 months (Table 1). The load factor fell month-to-month because of a combined decline in passenger travel (RPMs declined from July to August) and increase in capacity (Tables 3, 4, 5).
Trends:
Seasonally-adjusted
August was the sixth consecutive month in which ASMs and passenger enplanements reached seasonally-adjusted all-time highs (Tables 6, 8). RPMs declined 0.6 percent from July to August but remained at the second highest level (Tables 3, 4). Capacity rose 0.1 percent from July to August to reach the highest all-time level (Table 5). The August load factor (83.5) was the 10th highest all-time (Table 2).
Seasonally-adjusted trends are for the time period January 2000 to present.
Unadjusted
Systemwide: August load factor (86.4) was the second highest all-time monthly load factor, down from the all-time August high set in both 2012 and 2014 (86.5) (Table 13). The number of passengers, RPMs and ASMs all reached record highs for any August.
Domestic: August load factor (86.6) was down from the all-time August high set in 2014 (86.9). The number of passengers, RPMs and ASMs all reached record highs for any August.
International: August load factor (86.0) was down from the all-time August high set in 2013 (87.2). The number of passengers, RPMs and ASMs all reached record highs for any August.
The number of systemwide passengers, RPMs and ASMs all reached record highs for the first eight 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 fell 0.6 percent from July to August following following six months of growth from February to July (Table 3).
RPMs of 75.9 billion in August were the second all-time highest seasonally-adjusted total, 0.4 billion or 0.6 percent less than the all-time seasonally-adjusted high reached in July 2015. Eight of the top 10 all-time highest months for RPMs have been in 2015 and two were in 2014 (Table 4).
Seasonally-Adjusted Available Seat-Miles
ASMs rose 0.2 percent from July to August, the sixth consecutive month of growth (Table 5).
ASMs of 90.9 billion in August were the all-time highest seasonally-adjusted total. Six 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 0.7 percent from July to August, the sixth consecutive month of growth (Table 7). The systemwide total rose from July to August because of growth in domestic (0.7 percent) and international (0.1 percent) enplanements (Tables 9, 11).
Enplanements of 67.3 million in August 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 0.7 percent from July to August, the 12th consecutive month of growth (Table 9). Domestic enplanements in August (58.6 million) were the highest all-time seasonally-adjusted total. Six of the top 10 all-time highest months for domestic enplanements have been in 2015 (Table 9, 10).
International: U.S. airlines’ international enplanements rose 0.1 percent from July to August, the sixth consecutive month of growth. The August level (8.7 million) was the highest all-time seasonally-adjusted total. 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 86.4 percent in August, down from July and down from August 2014 (Table 13).
The August load factor of 86.4 was down 0.1 percent from the all-time unadjusted high for the month of August (86.5) reached in 2012 (Table 14).
Unadjusted Revenue Passenger-Miles
RPMs in August declined 3.4 percent from July but increased 4.9 percent from August 2014 (Table 15).
RPMs of 85.2 billion in August were the second all-time unadjusted high, or 3.4 percent less than the all-time unadjusted high reached 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 August declined 2.4 percent from July but increased 4.9 percent from August 2014 (Table 17).
ASMs of 98.6 billion in August were the second all-time unadjusted high, or 2.4 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 August 2015 (72.8 million) fell 3.7 percent from July and rose 4.7 percent from August 2014 (69.5 million) (Table 19).
The August 2015 systemwide enplanement total (72.8 million) was the second highest all-time unadjusted total, 3.7 percent less than the all-time unadjusted high reached in July 2015 (75.6 million). The August 2015 level was the all-time unadjusted high for the month of August (Table 20).

Domestic unadjusted passenger enplanements in August 2015 (62.8 million) were the third highest all-time unadjusted total, 3.6 percent less than the all-time unadjusted high reached in July 2015 (65.1 million). The August 2015 level was the all-time unadjusted high for the month of August (Table 22).
International: International unadjusted passenger enplanements in August 2015 (10.1 million) fell 3.9 percent from July and rose 3.3 percent from August 2014 (9.8 million) (Table 23).
International unadjusted passenger enplanements in August 2015 (10.1 million) were the third highest all-time unadjusted total, 3.9 percent less than the all-time unadjusted high reached in July 2015 (10.5 million). The August 2015 level was the all-time unadjusted high for the month of August (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.
