What the record says about this route
Cancellation, not delay, is the risk worth pricing here: 2.55% of scheduled flights never operated. A late flight still gets you there. A cancelled one leaves you rebooking, and on a route with few daily departures that can mean losing a day.
This route does worse than its own airport. IAD as a whole runs 16.3 points more punctual than these flights, which points at something specific to the route — the time of day it is scheduled, or the aircraft that feed it — rather than the airport.
This is a late route. Flights from Washington to Dallas/Fort Worth miss their scheduled arrival often enough that a tight connection at the far end is a connection at risk.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on IAD to DFW during March 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
