February 2015 U.S. Airline Traffic Data
Load Factor on All U.S. Scheduled Airlines (Domestic & International),
February 2010 - February 2015
The February load factor was below the all-time seasonally-adjusted high of 84.6 reached in January 2014 as well as the February 2014 level (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 as a result of a 0.1 percent increase in RPMs from January to February combined with a 1.0 percent decline 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 Not-Seasonally Adjusted 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
Load factor in February (84.2) was higher than in any month since the
peaks in January and February 2014. The February 2015 load factor was
the third highest all-time, just below the first two months of 2014 (Table
2). Load factors have generally increased since the recession because
passenger travel has increased at a faster pace than capacity. In February,
RPMs were at the second highest level, down from the all-time high set
in December but exceeding January, the third highest month. The last 10
months, starting with May 2014 through February 2015 are the 10 all-time
highest months for RPMs (Table 4).
Capacity declined in February from December, the highest all-time level, and from January, the eighth highest month, revised from last month’s Air Traffic press release. November, December and January are the only post-recession months among the top 10 for capacity, showing that after six years, capacity has returned to pre-recession levels (Table 6). Systemwide enplanements in February were the highest since the recession. February international enplanements were the fifth highest all-time. Domestic enplanements have been rising slowly but remain below pre-recession levels. Domestic enplanements in February were at the highest level since March 2008 (Tables 8, 10, 12).
Seasonally-adjusted trends are for the time period January 2000 to present.
Unadjusted
Systemwide: Load factor (80.2) was at an all-time high for the month of
February, exceeding the previous high set in 2014. Use, measured in RPMs
and in number of passengers, was at the highest February level since 2008.
Capacity, while up from February 2014, remained below the all-time highs
for the month of February set in 2008 and below the post-recession peak in 2012.
Domestic: Load factor (82.4) was at an all-time high for the month of February, exceeding the previous high set in 2013. Use and capacity were at the highest February level since 2008.
International: Load factor (75.3), while up from February 2014, was below the all-time February high set in 2013. Use reached all-time highs for the month of February, exceeding the highs set in 2014. Capacity, while up from 2014, was below the all-time high set in 2012.
Unadjusted trends are for the time period January 1996 to present. Data are available at Customize Table.
Seasonally-Adjusted Air Travel
Seasonally-Adjusted Revenue Passenger-Miles
RPMs rose 0.1 percent from January to February following a single month of decline from December to January (Table 3).
RPMs of 72.8 billion in February were the second highest all-time seasonally-adjusted total, 0.5 billion, or 0.6 percent, less than the all-time seasonally adjusted high reached in December 2014. Of the top 10 all-time highest months for RPMs, two have been in 2015 and eight were in 2014 (Table 4).
Seasonally-Adjusted Available Seat-Miles
ASMs fell 1.0 percent from January to February, the second consecutive month of decline (Table 5).
ASMs of 86.5 billion in February were 1.8 billion, or 2.1 percent, less than the all-time seasonally adjusted high reached in November 2007. Of the top 10 all-time highest months for ASMs, one has been in 2015 and two were in 2014 (Table 6).
Seasonally-Adjusted Passenger Enplanements
Systemwide: Systemwide passenger enplanements rose 0.1 percent from January to February,
the eighth consecutive monthly increase (Table 7). The systemwide total
rose from January to February because of growth in domestic enplanements
(0.1 percent). The growth took place despite a 0.2 percent decline in
international enplanements (Tables 9, 11).
Enplanements of 64.5 million in February were the third highest all-time seasonally-adjusted total, 0.4 million or 0.6 percent less than the all-time seasonally adjusted high reached in August 2007. Of the top 10 all-time highest months for enplanements, two have been in 2015 and one in 2014 (Table 8).
Domestic: Enplanements on domestic flights rose 0.1 percent from January to February, the second consecutive monthly increase (Table 9). Domestic enplanements in February (56.1 million) were 2.0 percent less than the all-time seasonally adjusted high reached in August 2007 (57.2 million). No post-recession month is among the top 10 all-time highest months for domestic enplanements (Table 10).
International: U.S. airlines’ international enplanements fell 0.2 percent from January to February after remaining relatively stable for two consecutive months. The February level (8.40 million) was the fifth highest all-time seasonally-adjusted total, 0.2 percent less than the all-time seasonally adjusted high reached in December 2014 (8.38 million). Two of the top 10 all-time highest months for international enplanements have been in 2015 and eight were in 2014 (Tables 11, 12).

Unadjusted Tables
Unadjusted Load Factor
U.S. airlines’ systemwide (domestic and international) scheduled
service load factor was 80.2 percent in February, up from January and
up from February 2014 (Table 13).
The February load factor of 80.2 was the all-time unadjusted high load factor for the month of February. The February load factor was below the all-time unadjusted high of 87.0 reached in June 2013. (Table 14)
The load factor rose year-over-year as a result of a 3.5 percent increase in RPMs from February 2014 to February 2015 combined with a 3.1 percent increase in ASMs (Tables 15, 17).
Unadjusted Revenue Passenger-Miles
RPMs in February declined 9.0 percent from January but increased 3.5 percent
from February 2014 (Table 15).
RPMs of 59.9 billion in February were 28.4 percent less than the all-time unadjusted high reached in July 2014. Of the top 10 all-time highest months for RPMs, none have been in 2015 and three were in 2014 (Table 16).
Unadjusted Available Seat-Miles
ASMs in February declined 10.2 percent from January but increased 3.1
percent from February 2014 (Table 17).
ASMs of 74.8 billion in February were 22.6 percent less than the all-time unadjusted high reached in July 2014. Of the top 10 all-time highest months for ASMs, none have been in 2015 and three were in 2014 (Table 18).
Unadjusted Passenger Enplanements
Systemwide: Systemwide unadjusted passenger enplanements in February 2015 (54.3 million)
fell 5.8 percent from January and rose 3.5 percent from February 2014
(Table 19).
The February 2015 systemwide enplanement total (54.3 million) was 25.1 percent, less than the all-time unadjusted high reached in July 2007 (72.4 million). Of the top 10 all-time highest months for enplanements, none have been in 2015 and two were in 2014 (Table 20).
Domestic: Domestic unadjusted passenger enplanements in February 2015 (47.2 million) were 25.6 percent less than the all-time unadjusted high reached in July 2007 (63.5 million) (Table 21).
Of the top 10 all-time highest months for domestic enplanements, none have been in 2015 and two were in 2014 (Table 22).
International: International unadjusted passenger enplanements in February 2015 (7.0 million) were 30.6 percent less than the all-time unadjusted high reached in July 2014 (10.1 million) (Table 23).
Of the top 10 all-time highest months for international enplanements, none have been in 2015 and three were 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.
