These figures cover 360 flights between September 2025 and August 2026. The median arrival is 18 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.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 2527 runs level with that at 90.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Arrival by arrival

How late AA 2527 runs when it is late

AA 2527 often beats the schedule: 197 of 348 completed flights, 57%, arrived 15 minutes or more early. Most of the lateness is short. 16 of the 32 late arrivals were under half an hour behind, and 7 reached an hour or more.

Share of 348 completed flights by arrival against schedule.

A late pushback is often recovered here: of 23 departures that left 15 minutes late or more, 9 still arrived on time. In the other direction, 18 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.

The worst days

Worst days for AA 2527

The latest arrival of the period was on 24 September 2025, 6 hours 31 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.

Delay causes

Why AA 2527 runs late

Carrier accounts for 56% of the 2,052 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
56%
National Airspace System
34%
Extreme weather
9%
Security
1%

34% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 698 minutes out of 2,052, against a national NAS share of 21%. The split is drawn from 2,052 delay minutes reported on AA 2527.

Cancellations run at 2.78%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.0% 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.

At 1,562 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 360 flights under AA 2527 in the data flew BOS to DFW. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 360 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 2527

For a booking, the cancellation rate is the figure to plan around on AA 2527: 2.78% of its 360 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
