The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today that U.S. airlines carried 63.1 million systemwide (domestic + international) scheduled service passengers in April 2014, 3.4 percent more than in April 2013. The systemwide total was the result of a 3.0 percent increase in the number of passengers on domestic flights (54.8 million) and a 6.2 percent increase in passengers on international flights (8.2 million) (Tables 1, 7, 13).

U.S. airlines carried 237.7 million systemwide (domestic + international) scheduled service passengers during the first four months of 2014, 1.6 percent more than during the same period in 2013 (Table 2). Domestically, U.S. airlines carried 206.0 million passengers, up 1.3 percent from 2013 (Table 8). Internationally, they carried 31.7 million passengers, up 3.7 percent from 2013 (Table 14). See Tables 2, 8 and 14 of Air Traffic Press Releases for previous-year data.

Load Factor

The April 2014 systemwide load factor (83.4 percent) was the all-time high for the month of April, exceeding the previous high of 82.5 set in 2012.  Load factor is a measure of the use of aircraft capacity that compares revenue passenger-miles (RPMs) as a proportion of available seat-miles (ASMs). Systemwide travel, measured by RPMs grew faster from April 2013 to April 2014 (up 4.0 percent) than the growth in capacity measured by ASMs (up 1.8 percent) (Table 1). The domestic load factor (84.9) was a record high for the month of April, topping the previous high of 83.6 recorded in 2012. Domestic RPMs grew faster from April 2013 to April 2014 (3.7 percent) than capacity (1.2 percent), resulting in the higher load factor (Table 7).

The international load factor (80.1) rose from 78.8 percent in April 2013 but was down from the highest April international load factor of 80.3 in April 2012.  International RPMs rose 4.7 percent from April 2013 to April 2014, outpacing the 3.0 percent growth in capacity, raising the load factor (Table 13).

Trends for the Month of April

Systemwide: For the month of April, the 2014 systemwide passenger total was the highest since 2008. RPMs were at the highest April level, exceeding the previous high in 2007.  Capacity measured in ASMs was at the third highest April level, below the April 2008 and 2007 levels.

Domestic: The April 2014 domestic passenger total was the highest since 2008 but was below the levels reached in the month of April from 2005 through 2008.  RPMs were at the second highest April level, below the April 2007 peak. Capacity measured in ASMs was the highest since 2008 but was below the levels reached in the month of April from 2004 through 2008. 

International: The number of passengers on U.S. airlines’ international flights was the highest on record for the month of April, exceeding the previous high in April 2012. RPMs were also at the highest April level, exceeding the previous high in April 2012. Capacity measured in ASMs was also at the highest April level, exceeding the previous high in April 2013.

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 79 carriers as of July 1 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 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. To create a customized table for passengers, flights, RPMs, ASMs and other data, including non-scheduled service, go to https://www.transtats.bts.gov/TRAFFIC/

For additional scheduled service numbers for U.S. airlines, U.S. and foreign airlines, by airline and by airport, see Passengers, Flights, Revenue Passenger-Miles, Available Seat-Miles and Load Factor.

For domestic numbers through April and international numbers through January by origin as well as by carrier, click on “Aviation,” then 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.

International totals in this press release consist of all U.S. carrier operations to and from the U.S. and from one foreign point to another foreign point. TranStats T-100 systemwide and international totals do not include U.S. carriers’ foreign point-to-point flights. For April, U.S. carriers reported 142,229 foreign point-to-point passengers. For January through April, U.S. carriers reported 660,789 foreign point-to-point passengers.

Data are subject to revision. BTS has scheduled Aug. 14 for the release of May traffic data. None of the data are from samples so measures of statistical significance do not apply.
