January 2016 US airline traffic data released

38

WASHINGTON, DC – The US Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today that US airlines’ system wide (domestic and international) scheduled service load factor – a measure of the use of airline capacity – fell to 83.9 percent in January, seasonally adjusted, falling after a single month of growth from November 2015 to December 2015. Seasonal adjustment allows the comparing of monthly load factors to all other months.

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 fell month-to-month as a result of a 0.5 percent decrease in RPMs from December to January combined with a smaller 0.1 percent decline in ASMs.
