2015 U.S.-Based Airline Traffic Data

Thursday, March 24, 2016

PDF | Excel

The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today that U.S. airlines and foreign airlines serving the United States carried an all-time high of 895.5 million systemwide (domestic and international) scheduled service passengers in 2015, 5.0 percent more than the previous record high of 853.1 million reached in 2014. The systemwide increase was the result of a 5.0 percent rise from 2014 in the number of passengers on domestic flights (696.2 million in 2015) and 4.7 percent growth from 2014 in passengers on U.S. and foreign airlines’ flights to and from the U.S. (199.4 million in 2015) (Tables 1, 1A, 5).

U.S. airlines carried 5.0 percent more passengers on domestic flights and 2.3 percent more passengers on international flights in 2015 than in 2014 for a systemwide increase of 4.7 percent. Foreign airlines carried 7.4 percent more passengers to and from the United States than in 2014. The 199.4 million passengers on international flights to and from the United States was a record high, exceeding the previous high set in 2014 (Tables 1A, 1B, 5).

This annual release includes preliminary data on U.S. carrier scheduled domestic and international service, and foreign carrier scheduled international service to and from the United States. BTS regular monthly air traffic releases include data on U.S. carrier scheduled service only. For U.S. domestic service data for 2015, see the BTS December Air Traffic press release.

Airlines with Most Passengers in 2015
American Airlines carried more total system passengers in 2015 than any other U.S. airline. American also carried more passengers on international flights to and from the U.S. in 2015 than any other U.S. or foreign carrier. American’s passenger numbers include passengers reported as US Airways for the first six months of 2015. British Airways carried the most passengers on flights to and from the U.S. of any foreign airline (Tables 3 and 7).

U.S. Airports with Most Passengers in 2015
More total system passengers boarded planes in 2015 at Atlanta Hartsfield-Jackson International than at any other U.S. airport. More passengers boarded international flights at New York John F. Kennedy than at any other U.S. airport (Tables 4 and 8).

Load Factor and Capacity
From 2014 to 2015, systemwide demand, measured in Revenue Passenger-Miles, (RPMs), and capacity, measured in Available Seat-Miles (ASMs), both grew by 5.5 percent. As a result, load factor remained flat at 82.7, which was the highest annual systemwide load factor on record for U.S. carriers and foreign carriers serving the United States (Table 1). 

Demand on international flights, measured in RPMs, rose 5.1 percent in 2015, less than the 5.7 percent rise in capacity measured in ASMs. The result was a decline in the international load factor to 80.5 from 81.0 in 2014 (Table 5).

For annual airline and airport statistics, Tables 1 through 4 provide combined domestic and international travel statistics, and Tables 5 through 8 provide international travel statistics.

Reporting Notes
Data are compiled from monthly reports filed with BTS by commercial U.S. and foreign air carriers detailing operations, passenger traffic and freight traffic. This release includes data received by BTS from 203 carriers as of March 16 for U.S. and foreign carrier scheduled civilian operations. See the complete list of reporting and non-reporting carriers

American and US Airways, following their December 2013 merger announcement, began reporting joint data in July 2015.

For additional passenger, flight, Revenue Passenger-Miles, Available Seat-Miles, load factor and freight numbers, go to the Airlines and Airports page and use the Quick Links. International totals and results for foreign carriers may differ from the press release until the next database update scheduled for April 16. Also, the web tables do not include U.S. carrier foreign point-to-point operations. For 2015, U.S. carriers reported 1,300,036 foreign point-to-point passengers.

To create a customized table for U.S. carrier passengers, flights, RPMs, ASMs and other data, including non-scheduled service, go to BTS Air Carrier Traffic Statistics.

Additional traffic numbers are available on the BTS website at TranStats. Click on “Aviation.”  For U.S. carrier system passengers, RPMs and ASMs by carrier through December, click on “Air Carrier Summary Data (Form 41 and 298C Summary Data),” and then click on “Schedule T-1.” Use crosstabs to find scheduled service.

For domestic numbers through December and international numbers through September by origin as well as by carrier, after clicking on “Aviation,” click on “Air Carrier Statistics (Form 41 Traffic).”  Click on “T-100 Market” for system passenger numbers, “T-100 Domestic Market” for domestic or “T-100 International Market” for international. For flights, stage length and trip length, use the appropriate T-100 Segment database. Use crosstabs to find scheduled service. Complete international data for the full year 2015 will be released on June 16.

TranStats system and international totals do not include U.S. carriers’ foreign point-to-point flights. None of the data are from samples so measures of statistical significance do not apply. Data in this press release is not seasonally adjusted.
