Connections and routes
What a delay on this flight costs
15.1% 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 one other city pair in the data, including TPA to ATL (17), but none flew often enough under DL 1457 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to TPA only.
One caution: this is a thin sample. 360 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 DL 1457
For a booking, DL 1457 is a flight to put a long connection behind. 15.1% 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.
