4. Introduction
Monthly Performance Report: February 2012
The masFlight Monthly Performance Report summarizes United States airline performance.
Differences from DOT ASQP (“On-Time”) Reports. We collect flight information for most scheduled
carriers, including both “mainline” hub-and-spoke airlines and their regional affiliates. DOT’s on-time
data reports differ from ours because:
(1) Some carriers are excluded from DOT reports. Only airline certificates with 1% or greater
share of scheduled-service domestic passenger revenue report on-time data to DOT. Many low
fare and regional carriers are therefore excluded. Our report captures most of these carriers.
(2) Our report includes international flights by U.S. carriers. DOT includes only domestic flight
operations in its report, since carriers do not report international flights.
(3) DOT reports on-time performance by operating carrier, not by marketing carrier. For
example, both United and Delta market regional flights that are operated by SkyWest. We report
performance by operating carrier (e.g. SkyWest as a discrete entity) and by marketing carrier.
(4) DOT reports focus on on-time arrivals only. We focus on three operational statistics.
“D15” performance is the percent of flights that depart the gate within 15 minutes of schedule.
“A14” performance is the percent that arrive at the destination gate within 14 minutes of schedule.
“CF” (or Completion Factor) is the percent of flights scheduled that arrive at their destination,
net of cancellations and non-completed diversions.
