Definition
A U.S. Department of Transportation reporting system that collects and publishes monthly data from major U.S. airlines on operational service quality, including on-time arrivals and departures, flight cancellations, mishandled baggage, and oversales. The data feeds the DOT's Air Travel Consumer Report.
Plain English
A government program that tracks how well airlines are running — whether flights are on time, how often bags get lost, and how often passengers get bumped — and publishes the results each month.
Context Anchor
Seen in FAA acronym lists and in airline operations or performance-reporting discussions, rather than as a normal cockpit control or maneuver term.
Why Pilots Care
Airline pilots fly under operational pressures shaped in part by ASQP metrics. On-time performance numbers reported through this system influence schedule design, dispatch decisions, and company culture around departure pushes.
Intuition Check
Do not read “service quality” as only friendliness or comfort. In airline use, it also includes whether the airline’s scheduled service is being delivered reliably.
Example Sentence 1
The carrier reviewed its ASQP data each month to identify which routes were dragging down its on-time arrival rate.
Example Sentence 2
ASQP reports help airlines spot recurring delay problems on specific routes.
