Connections and routes

What a delay on this flight costs

11.6% 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 FLG to PHX (27), but none flew often enough under OO 6474 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PHX to FLG only.

One caution: this is a thin sample. 275 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 6474

For a booking, read OO 6474 as 76.1% on time with 2.18% cancelled over 275 flights. Those are rates from the past twelve months, not a forecast for any particular day.
