These figures cover 327 flights between September 2025 and August 2026. The median arrival is 15 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 April 2026 | 10 hours 43 minutes | Carrier |
| 28 February 2026 | 7 hours 32 minutes | Carrier |
| 1 July 2026 | 6 hours 37 minutes | Late-arriving aircraft |

Delay causes
Why AA 2771 runs late
Carrier accounts for 66% of the 3,566 delay minutes carriers reported here, and the remaining four split what is left.
- 66%Carrier
- 17%National Airspace System
- 15%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,371 of the 3,566 delay minutes reported here. The split is drawn from 3,566 delay minutes reported on AA 2771.
Cancellations are rare at 0.61%, below the national 1.89% 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
Badly late arrivals are rare here: only 4.6% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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.
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
For a booking, AA 2771 has one of the better records a US domestic flight can show: 87.9% on time and 0.61% cancelled. That is a base rate, not a promise about any single day.
