Monthly Performance Report: March 2013
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.

records for 82,000+ global flight operations daily.
About masFlight and Marks Systems
masFlight data can be used to gain insight to aviation operations questions
through improved competitive environment context and transparency.
masFlight goes far beyond U.S. DOT and typical FLIFO data sets. We
collect and consolidate operational data for virtually all U.S. carriers and for
many global airlines, allowing apples-to-apples comparisons.
We link contextual information including published
schedules, weather, airport configuration, and fleet registries to individual
flights, allowing analysts to focus queries on relevant metrics or constraints.
We are a team of experienced aviation operations analysts who
understand the importance of data integrity and accuracy. We multi-source
our information and extensively validate and reconcile new data.
Our portfolio of solutions makes accessing masFlight data easy.
