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 – rose to 83.2 percent in June, seasonally adjusted, after remaining unchanged for two 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), June 2010 - June 2015

For June, U.S. airlines reported seasonally-adjusted all-time monthly highs in passenger enplanements, Revenue Passenger-Miles (RPMs) and Available Seat-Miles (ASMs). Systemwide passenger enplanements in June (66.0 million) exceeded the previous record in May 2015 by 0.2 percent (Table 8). Systemwide RPMs in June (74.8 billion) exceeded the previous record in May 2015 by 0.4 percent (Table 4). Systemwide ASMs in June (89.9 billion) exceeded the previous record in May 2015 by 0.1 percent (Table 6). These all-time highs resulted in a higher load factor in June because the growth in passenger travel exceeded the growth in airline capacity.

The June load factor of 83.2 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 rose in June after having remained stable at 82.9 in April and May (Table 1). The load factor rose from May to June because passenger travel grew faster (0.4 percent increase in RPMs) than system capacity (0.1 percent increase in ASMs) (Tables 3, 5).

Trends:
Seasonally-adjusted
Since peaking in early 2014, load factor has varied from a high of 83.8 in May 2014 to a low of 82.6 in November 2014. The June load factor (83.2) continued that pattern (Table 1). June was the fourth consecutive month in which RPMs, ASMs and passenger enplanements reached seasonally-adjusted all-time highs (Tables 4, 6, 8).

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

Unadjusted
Systemwide: June load factor (86.4) was down from the all-time June high set in 2013 (87.0) (Table 13). The number of passengers, RPMs and ASMs all reached record highs for any June.

Domestic: June load factor (87.4) equaled the all-time high for the month of June set in 2014. The number of passengers, RPMs and ASMs all reached record highs for any June.

International: June load factor (84.4) was down from the all-time June high set in 2013 (86.9). The number of passengers, RPMs and ASMs all reached record highs for any June.

For the first half of 2014, January through June, load factor (82.9) was down from the all-time high set in 2014 (83.2). The number of passengers, RPMs and ASMs all reached record highs for the first six 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 May to June, the fifth consecutive month of growth (Table 3).

RPMs of 74.8 billion in June were the highest all-time seasonally-adjusted total. Six of the top 10 all-time highest months for RPMs have been in 2015 and four were in 2014 (Table 4).  

Seasonally-Adjusted Available Seat-Miles

ASMs rose 0.1 percent from May to June, the fourth consecutive month of growth (Table 5).

ASMs of 89.9 billion in June were the highest all-time seasonally-adjusted total. Five 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 0.2 percent from May to June, rising for the fourth consecutive month (Table 7). The systemwide total rose from May to June because of growth in domestic (0.1 percent) and international enplanements (0.8 percent) (Tables 9, 11).

Enplanements of 66.0 million in June were the highest all-time seasonally-adjusted total. Six of the top 10 all-time highest months for enplanements have been in 2015 (Table 8).

Domestic: Enplanements on domestic flights rose 0.1 percent from May to June, rising for the 12th consecutive month (Table 9). Domestic enplanements in June (57.5 million) were the highest all-time seasonally-adjusted total. Four of the top 10 all-time highest months for domestic enplanements have been in 2015. No other post-recession months are among the top 10 all-time highest months for domestic enplanements (Table 10).

International: U.S. airlines’ international enplanements rose 0.8 percent from May to June, rising for the third consecutive month (Table 11). The June level (8.5 million) was the highest all-time seasonally-adjusted total. Six of the top 10 all-time highest months for international enplanements have been in 2015 and four 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 June, up from May and unchanged from June 2014 (Table 13).

The June load factor of 86.4 was down from the all-time unadjusted high for any month, 87.0 in June 2013 (Table 14)

The load factor rose year-to-year because passenger travel grew faster (4.1 percent increase in RPMs) than system capacity (4.0 percent increase in ASMs) (Tables 15, 17).

Unadjusted Revenue Passenger-Miles

RPMs in June increased 6.0 percent from May and increased 4.1 percent from June 2014 (Table 15).

RPMs of 82.7 billion in June were the second all-time unadjusted high, or 1.2 percent less than the all-time unadjusted high reached in July 2014. One of the top 10 all-time highest months for RPMs has been in 2015 and three were in 2014. The June 2015 level was the all-time unadjusted high for the month of June (Table 16). 

Unadjusted Available Seat-Miles

ASMs in June increased 3.1 percent from May and increased 4.0 percent from June 2014 (Table 17).

ASMs of 95.7 billion in June were the second all-time unadjusted high, or 0.9 percent less than the all-time unadjusted high reached in July 2014. Two of the top 10 all-time highest months for ASMs have been in 2015 and two were in 2014. The June 2015 level was the all-time unadjusted high for the month of June (Table 18). 

Unadjusted Passenger Enplanements
Systemwide: Systemwide unadjusted passenger enplanements in June 2015 (71.3 million) rose 3.4 percent from May and 3.9 percent from June 2014 (Table 19).

The June 2015 systemwide enplanement total (71.3 million) was the fourth highest all-time unadjusted total, 1.6 percent less than the all-time unadjusted high in July 2007 (72.4 million). The June 2015 level was the all-time unadjusted high for the month of June (Table 20).

Domestic: Domestic unadjusted passenger enplanements in June 2015 (61.8 million) rose 2.6 percent from May (60.3 million) and rose 4.3 percent from June 2014 (59.3 million) (Table 21).

Domestic, unadjusted passenger enplanements in June 2015 (61.8 million) were the fourth highest all-time unadjusted total, 2.6 percent less than the all-time unadjusted high in July 2007 (63.5 million) (Table 21). The June 2015 level was the all-time unadjusted high for the month of June (Table 22).

International: International unadjusted passenger enplanements in June 2015 (9.5 million) rose 9.0 percent from May (8.7 million) and rose 1.3 percent from May 2014 (9.3 million) (Table 23).

International unadjusted passenger enplanements in June 2015 (9.5 million) were the seventh highest all-time unadjusted total, 6.7 percent less than the all-time unadjusted high in July 2014 (10.1 million) (Table 23). The June 2015 level was the all-time unadjusted high for the month of June (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 and 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.
