AA 1404 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 3.2 hours on average. That is a workable record, not a spotless one. That rests on 343 flights, with a median arrival 3 minutes early.

These figures cover 343 flights between July 2025 and June 2026. The median arrival is 3 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When AA 1404 flies

AA 1404 flies DEN to PHX without a single fixed slot. Its most common scheduled departure was 07:50, used on 67 of 343 flights, with 07:10 (51 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 07:50 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 1404 runs 9 points worse at 80.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 1404 quarter by quarter

AA 1404 did not run the same all year. Its best quarter was Jul–Sep 2025 at 85.5% on time and its weakest Jan–Mar 2026 at 70.8%, a swing of 15 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.

Jul–Sep 202584 flights85.5%
Oct–Dec 202588 flights82.8%
Jan–Mar 202689 flights70.8%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, AA 1404 did best on Wednesday at 89.5% on time and worst on Tuesday at 73.6%. Each day rests on about 49 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 1404 runs late

One category carries most of the weight here. Carrier accounts for 69% of the 13,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 8,991 of the 13,000 delay minutes reported here. The split is drawn from 13,068 delay minutes reported on AA 1404.

Cancellations are rare at 0.87%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

7.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 3.2 hours, which a normal layover absorbs.

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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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. 343 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 80.0% on time with 0.87% cancelled over 343 flights. Those are rates from the past twelve months, not a forecast for any particular day.
