Historical statistics for July 2025 to June 2026, not live status. For today’s AA 727, check with American Airlines.

AA 727 earns a D, which is as low as this site's scale goes for a reason. Only 56.5% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 361 flights, with a median arrival 7 minutes late.

The national on-time rate over the same period is 77.6%, so AA 727 runs 21 points behind the country as a whole. Across a thousand flights that is about 211 extra late arrivals.

These figures cover 361 flights between July 2025 and June 2026. Beyond the headline rate, 18.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AA 727 flies

AA 727 flies DFW to SEA without a single fixed slot. Its most common scheduled departure was 14:40, used on 92 of 361 flights, with 17:15 (44 flights) and 14:25 (41 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 14:40 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AA 727 runs 16 points worse at 56.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

AA 727 next to DFW to SEA

Across the year

AA 727 quarter by quarter

AA 727 did not run the same all year. Its best quarter was Jul–Sep 2025 at 62.0% on time and its weakest Apr–Jun 2026 at 49.4%, a swing of 13 points on roughly 90 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 202592 flights62.0%
Oct–Dec 202589 flights54.5%
Jan–Mar 202689 flights60.0%

Scale runs 40% to 65%. Rows with fewer than 30 flights show a dash.

By weekday, AA 727 did best on Tuesday at 62.7% on time and worst on Sunday at 46.0%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 727 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 11,000 reported delay minutes.

Late-arriving aircraft
40%
Carrier
38%
National Airspace System
11%
Extreme weather

Security
0%

40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 11,000 reported delay minutes here, that single category outweighs weather by 4 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 11,386 delay minutes reported on AA 727.

Cancellations sit at 2.49% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 18.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 1,660 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.

The same number turns up on one other city pair in the data, including SEA to DFW (166), but none flew often enough under AA 727 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to SEA only.

One caution: this is a thin sample. 361 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 727

For a booking, AA 727 is a flight to put a long connection behind. 18.5% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
