Connections and routes
What a delay on this flight costs
18.3% 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.
Every one of the 271 flights under B6 1905 in the data flew FLL to TPA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 271 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 B6 1905
For a booking, B6 1905 is a flight to put a long connection behind. 18.3% 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.
