Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1455, check with American Airlines.
AA 1455 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 350 flights, with a median arrival 6 minutes late.
The national on-time rate over the same period is 77.6%, so AA 1455 runs 17 points behind the country as a whole. Across a thousand flights that is about 175 extra late arrivals.

These figures cover 350 flights between July 2025 and June 2026. Beyond the headline rate, 17.2% 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 1455 flies
AA 1455 flies DFW to MSY without a single fixed slot. Its most common scheduled departure was 21:05, used on 48 of 350 flights, with 21:16 (44 flights) and 21:07 (37 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 21:05 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and AA 1455 runs 10 points worse at 60.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AA 1455 quarter by quarter
AA 1455 did not run the same all year. Its best quarter was Jan–Mar 2026 at 68.8% on time and its weakest Apr–Jun 2026 at 52.9%, a swing of 16 points on roughly 88 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.

- Oct–Dec 202585 flights65.5%
- Jan–Mar 202687 flights68.8%
- Apr–Jun 202691 flights52.9%
Scale runs 45% to 75%. Rows with fewer than 30 flights show a dash.
By weekday, AA 1455 did best on Tuesday at 71.4% on time and worst on Sunday at 44.4%. Each day rests on about 50 flights, so a gap of 27 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1455 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 60% of the 9,469 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.
- 60%Late-arriving aircraft
- 27%Carrier
- 8%Extreme weather
- 6%National Airspace System
60% 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 9,469 reported delay minutes here, that single category outweighs weather by 8 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 9,469 delay minutes reported on AA 1455.
Cancellations run at 5.14%, against 1.81% nationally. That is about one flight in twenty 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.2% 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.
The same number turns up on three other city pairs in the data, including MSY to DFW (11), ELP to DFW (3) and DFW to ELP (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: 5.14% of its 350 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.
