Connections and routes
What a delay on this flight costs
12.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The same number turns up on two other city pairs in the data, including ORD to BNA (4) and PSP to LAX (2), but none flew often enough under OO 5494 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to AMA only.
One caution: this is a thin sample. 318 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking OO 5494
For a booking, OO 5494 is a flight to put a long connection behind. 12.5% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
