Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2771, check with American Airlines.
AA 2771 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 327 flights, with a median arrival 13 minutes early.
Set against the rest of the country, AA 2771's record is 10 points better than the US average of 77.6%. That gap is worth roughly 99 fewer late arrivals for every thousand flights.

These figures cover 327 flights between July 2025 and June 2026. The median arrival is 13 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 2771 flies
AA 2771 flies DEN to ORD without a single fixed slot. Its most common scheduled departure was 07:22, used on 59 of 327 flights, with 07:00 (47 flights) and 07:36 (43 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 07:22 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 2771 runs level with that at 87.5%. 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 2771 quarter by quarter
AA 2771 did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.3% on time and its weakest Oct–Dec 2025 at 81.1%, a swing of 12 points on roughly 82 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 2771 did best on Friday at 95.6% on time and worst on Sunday at 80.9%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 2771 runs late
One category carries most of the weight here. Carrier accounts for 68% of the 3,845 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.
- 68%Carrier
- 17%Late-arriving aircraft
- 14%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 68%, 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 2,605 of the 3,845 delay minutes reported here. The split is drawn from 3,845 delay minutes reported on AA 2771.
Cancellations sit at 1.53% against a national 1.81%, which is ordinary. Diversions add another 0.61%.
Connections and routes
What a delay on this flight costs
5.3% 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 an hour and a half, which a normal layover absorbs.
The 888 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 two other city pairs in the data, including CLT to ILM (37) and ILM to CLT (37), but none flew often enough under AA 2771 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to ORD only.
One caution: this is a thin sample. 327 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 2771
