What the record says about this route
Which airline you fly changes the odds here. United Airlines arrived on time 11.1 points more often than American Airlines over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
Cancellation, not delay, is the risk worth pricing here: 2.97% 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 is a late route. Flights from Denver to Dallas/Fort Worth miss their scheduled arrival often enough that a tight connection at the far end is a connection at risk.
This is a thin route — 539 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.
Which airline should you fly on this route?
Over March 2025 – August 2026, United Airlines arrived on time most often on DEN to DFW. American Airlines was late most often.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on DEN 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 →
