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 83.4 percent in October, seasonally adjusted,  after having remained virtually unchanged at 83.3 percent for two months (Table 1). Seasonal adjustment allows the comparison of monthly load factors to all other months.

Load Factor on All U.S. Scheduled Airlines (Domestic & International),
October 2009 - October 2014

Table Version | Excel

Load Factor on All U.S. Scheduled Airlines (Domestic & International), October 2009 - October 2014

The October seasonally-adjusted load factor was the ninth highest all-time but remained below levels of early 2014 when the January and February load factors reached all-time highs. The October load factor was the highest since May (Tables 1, 2). Load factor is a measure of the use of aircraft capacity that compares system demand, measured in Revenue Passenger-Miles (RPMs) as a proportion of system capacity, measured in Available Seat-Miles (ASMs).

The load factor rose from September to October as a result of RPMs increasing slightly more than ASMs (0.5 percent and 0.3 respectively) (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.  Click on a link in the Quick Links box on the right.  For more historical data, see Traffic on the BTS website.

Trends:

Seasonally-adjusted

Systemwide load factors continue to trend upwards with five of the top 10 months with the highest load factors, including the top two, taking place in 2014 (Table 2).   Load factors have increased because demand, measured in RPMs, has increased at a faster pace since the recession than capacity, measured in ASMs. Demand in October 2014 is the highest on record while capacity in October 2014 reached its highest level since the recession. Nine of the top 10 months for demand took place this year while only two of the top 10 months for capacity were in 2014. July 2014 and October 2014 are the only post-recession months on the top 10 list for capacity (Tables 4, 6).

Systemwide enplanements also remain below pre-recession levels, held down by the slow growth in domestic enplanements (Tables 8, 10). The record levels of international enplanements in 2014 combined with all-time highs in RPMs shows a greater emphasis on longer distance flights (Table 12).

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

Unadjusted

Systemwide: For the month of October, the 2014 passenger total (64.3 million) is the highest on record, topping the previous high set in 2007. October was the second consecutive month with a record high for that month, following the record September high in the previous month. Demand, measured in RPMs, was at the highest October level, exceeding the previous record set in 2013.  Demand has exceeded pre-recession levels for every month of 2014 except February. Capacity, measured in ASMs, was at the second highest October level, but was below the all-time high reached in October 2007.

Domestic: The October 2014 domestic passenger total (56.9 million) is the second highest October level, but was below the October 2007 level. Demand, measured in RPMs, reached an all-time high for October, exceeding the previous high in October 2007. Capacity was the highest since 2008 but was below the all-time October high reached in 2007. 

International: The October 2014 international passenger total (7.4 million) and demand were at the second highest October level, but were below the October 2013 level. Capacity on was the highest on record for the month of October, exceeding the previous high in October 2013.

Unadjusted trends are for the time period January 1974 to present.

 

Seasonally-Adjusted Air Travel

Seasonally-Adjusted Revenue Passenger-Miles

RPMs rose 0.5 percent from September to October, increasing after remaining unchanged for two consecutive months (Table 3).

October RPMs (72.5 billion) were the highest all-time seasonally-adjusted total.  Nine of the top 10 all-time highest months for RPMs have been in 2014 (Table 4).  

Seasonally-Adjusted Available Seat-Miles

ASMs rose 0.3 percent from September to October, increasing after having remained virtually unchanged for two consecutive months to reach the highest level since March 2008 (Table 5).

ASMs of 86.9 billion in October were the eighth highest all-time seasonally-adjusted total, 1.6 percent less than the all-time seasonally-adjusted high in November 2007.  Two of the top 10 all-time highest months for ASMs have been in 2014 (Table 6).

Seasonally-Adjusted Passenger Enplanements

Systemwide: Systemwide passenger enplanements remained virtually unchanged from September to October following a single month of growth from August to September. Enplanements in September were at the highest level since the recession (Table 7).

October enplanements (63.9 million) were down 1.5 percent from the all-time seasonally-adjusted high in August 2007.  None of the top 10 all-time highest months for enplanements have been in 2014 (Table 8).

Domestic: Enplanements on domestic flights rose 0.1 percent from September to October, increasing for the second consecutive month (Table 9). Domestic enplanements in October (55.7 million) were down 2.7 percent from the all-time seasonally-adjusted high in August 2007 (57.2 million) and the highest level since the recession. No 2014 months are among the top 10 all-time highest months for domestic enplanements (Table 10).

International: U.S. airlines’ international enplanements fell 0.6 percent from September to October, falling for the fourth consecutive month. The October level (8.2 million) was 2.4 percent less than the all-time seasonally-adjusted high in June 2014 (8.4 million). Eight of the top 10 all-time highest months for international enplanements took place 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 82.8 percent in October, up from 81.9 in September and 82.2 in October 2013 (Table 13).

The October load factor of 82.8 was down from the all-time unadjusted high for the month of October of 83.4 set in 2012. The October load factor was below the all-time unadjusted high of 87.0 in June 2013 (Table 14).

The load factor rose year-to-year as a result of a 3.0 percent increase in demand, measured in RPMs, from October 2013 to October 2014 combined with a 2.2 percent increase in capacity, measured in ASMs (Tables 15, 17).

Unadjusted Revenue Passenger-Miles

RPMs in October rose 4.0 percent from September and 3.0 percent from October 2013. For the month of October, the 2014 RPM total (71.1 billion) was the highest on record, topping the previous high set in 2013 (Table 15).

RPMs of 71.1 billion were reported in October, 15.0 percent less than the all-time high, unadjusted, in July 2014.  Three of the top 10 all-time highest months for RPMs have been in 2014 (Table 16). 

Unadjusted Available Seat-Miles

ASMs in October rose 2.8 percent from September and 2.2 percent from October 2013 (Table 17).

ASMs of 85.9 billion were reported in October, 11.0 percent less than the all-time high, unadjusted, in July 2014.  Three of the top 10 all-time highest months for ASMs have been in 2014 (Table 18).  The October 2014 level was down 1.2 percent from the all-time October high in 2007.

Unadjusted Passenger Enplanements

Systemwide: Unadjusted passenger enplanements in October 2014 (64.3 million) rose 7.3 percent from September and 3.4 percent from October 2013 (Table 19).

The October 2014 systemwide enplanement total (64.3 million) was 11.2 percent less than the all-time unadjusted high in July 2007 (72.4 million). For the month of October, the 2014 systemwide passenger total (64.3 million) was the highest on record, topping the previous high set in 2007 (Table 20).

Domestic: Domestic unadjusted passenger enplanements in October 2014 (56.9 million) were 10.3 percent less than the all-time unadjusted high in July 2007 (63.5 million) (Table 21).

The October 2014 level was down from the all-time unadjusted high for the month of October of 57.2 million set in 2007 (Table 22).

International: International unadjusted passenger enplanements in October 2014 (7.4 million) were 26.9 percent less than the all-time unadjusted high in July 2014 (10.1 million) (Table 23).

The October 2014 level was down from the all-time unadjusted high for the month of October of 7.5 million set in 2013 (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. See data for airline data since 2000 as well as seasonally-adjusted data for rail, transit, pipelines, trucking and waterways.

 

Reporting Notes

Data are compiled from monthly reports filed with BTS by commercial U.S. air carriers detailing operations, passenger traffic and freight traffic. This release includes data received by BTS from 80 carriers as of Jan. 6 for U.S. carrier scheduled civilian operations.

Southwest and AirTran Airways are reporting as separate carriers with the exception of their financial reports.  They have one FAA SOC (single operating certificate), requiring that they utilize the same safety/operating procedures, but they have separate DOT 401 economic certificates, meaning they remain operating as separate economic entities.

Go to http://www.transtats.bts.gov/releaseinfo.asp for the complete list of reporting and non-reporting carriers. U.S. carriers’ foreign point-to-point flights are included in system and international totals.
