Connections and routes
What a delay on this flight costs
10.2% 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 1,107 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on four other city pairs in the data, including PHX to SEA (245), DTW to BUF (1) and VPS to DTW (1), but none flew often enough under DL 2449 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to PHX only.
One caution: this is a thin sample. 250 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 2449
For a booking, read DL 2449 as 78.8% on time with 2.00% cancelled over 250 flights. Those are rates from the past twelve months, not a forecast for any particular day.
