Across the year
AA 1404 quarter by quarter
AA 1404 did not run the same all year. Its best quarter was Oct–Dec 2025 at 82.8% on time and its weakest Jan–Mar 2026 at 70.8%, a swing of 12 points on roughly 86 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, AA 1404 did best on Saturday at 83.0% on time and worst on Tuesday at 70.6%. Each day rests on about 49 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Connections and routes
What a delay on this flight costs
10.3% 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.
The 602 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 one other city pair in the data, including IND to DFW (1), but none flew often enough under AA 1404 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to PHX only.
One caution: this is a thin sample. 344 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 AA 1404
For a booking, read AA 1404 as 77.3% on time with 1.45% cancelled over 344 flights. Those are rates from the past twelve months, not a forecast for any particular day.
