Across the year
AA 1455 quarter by quarter

Delay causes
Why AA 1455 runs late
Late-arriving aircraft accounts for 59% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 30%Carrier
- 5%Extreme weather
- 5%National Airspace System
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 12,846 delay minutes reported on AA 1455.
Cancellations run at 3.71%, against 1.89% nationally. That is about one flight in 25 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
18.8% 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.
The same number turns up on three other city pairs in the data, including MSY to DFW (11), DFW to ELP (3) and ELP to DFW (3), but none flew often enough under AA 1455 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to MSY only.
One caution: this is a thin sample. 350 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 1455
For a booking, the cancellation rate is the figure to plan around on AA 1455: 3.71% of its 350 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
