What the record says about this route

The season swings this route hard. In December it ran 58.1 points more punctual than in June — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.

The route has been getting worse. The later months run 14.5 points less punctual than the earlier ones. A drift of that size is rarely weather; it is more often an airline adding frequencies faster than the airports can absorb them.

The two directions do not behave alike. RDU to DAL arrives on time 8.5 points more often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.

This is a late route. Flights from Dallas to Raleigh/Durham miss their scheduled arrival often enough that a tight connection at the far end is a connection at risk.

Which airline should you fly on this route?

Over January 2025 – August 2026, Southwest Airlines arrived on time most often on DAL to RDU. Flights ran closest to schedule in December and worst in June.

What these figures do and do not tell you

Everything on this page is counted from the flights that actually operated on DAL to RDU during January 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 →
