What the record says about this route

Which airline you fly changes the odds here. Republic Airways arrived on time 10.2 points more often than SkyWest 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.

The season swings this route hard. In October it ran 24 points more punctual than in January — 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 two directions do not behave alike. CVG to RDU arrives on time 7 points less 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 route does better than its own airport. Departures from RDU overall run 7.2 points less punctual than this particular one — so whatever congestion RDU has, this route is largely escaping it.

Which airline should you fly on this route?

Over July 2024 – July 2026, Republic Airways arrived on time most often on RDU to CVG. SkyWest Airlines was late most often. Flights ran closest to schedule in October and worst in January.

What these figures do and do not tell you

Everything on this page is counted from the flights that actually operated on RDU to CVG during July 2024 – July 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 →
