AA 2527 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 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 360 flights, with a median arrival 19 minutes early.

Set against the rest of the country, AA 2527's record is 13 points better than the US average of 77.6%. That gap is worth roughly 134 fewer late arrivals for every thousand flights.

These figures cover 360 flights between July 2025 and June 2026. The median arrival is 19 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 2527 flies

AA 2527 flies BOS to DFW without a single fixed slot. Its most common scheduled departure was 06:00, used on 153 of 360 flights, with 05:30 (99 flights) and 05:00 (36 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 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 91.0%. 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 2527 quarter by quarter

Quarter by quarter AA 2527 held fairly steady: 93.0% in Jul–Sep 2025, 88.8% in Oct–Dec 2025, 91.5% in Jan–Mar 2026 and 90.8% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 2527 did best on Wednesday at 96.1% on time and worst on Saturday at 83.7%. Each day rests on about 51 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 2527 runs late

One category carries most of the weight here. Carrier accounts for 59% of the 2,144 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.

59%

Extreme weather

The largest share of delay minutes, 59%, 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 1,264 of the 2,144 delay minutes reported here. The split is drawn from 2,144 delay minutes reported on AA 2527.

Cancellations run at 3.61%, against 1.81% nationally. That is about one flight in 30 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 2.3% land an hour or more behind schedule, against 8.1% 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: 3.61% of its 360 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
