AA 727 earns an F, which is as low as this site's scale goes for a reason. Only 54.8% of flights arrive inside the 15-minute window, 23 points worse than the national rate of 77.3%. 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 10 minutes late.
The national on-time rate over the same period is 77.3%, so AA 727 runs 23 points behind the country as a whole. Across a thousand flights that is about 225 extra late arrivals.

Delay causes
Why AA 727 runs late
Late-arriving aircraft accounts for 47% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 34%Carrier
- 11%National Airspace System
- 7%Extreme weather
- 1%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 12,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 12,113 delay minutes reported on AA 727.
Cancellations sit at 2.49% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
18.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 (165), 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.
