Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1279, check with American Airlines.
AA 1279 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 282 flights, with a median arrival 12 minutes early.

These figures cover 282 flights between July 2025 and June 2026. Beyond the headline rate, 9.2% 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 1279 flies
AA 1279 flies CMH to DFW without a single fixed slot. Its most common scheduled departure was 11:36, used on 67 of 282 flights, with 11:35 (44 flights) and 11:43 (32 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 11:36 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AA 1279 runs level with that at 80.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AA 1279 quarter by quarter
Quarter by quarter AA 1279 held fairly steady: 79.0% in Jul–Sep 2025, 82.7% in Oct–Dec 2025, 81.0% in Jan–Mar 2026 and 77.8% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 1279 did best on Tuesday at 87.8% on time and worst on Monday at 70.7%. Each day rests on about 40 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1279 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 58% of the 4,583 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.
- 58%Late-arriving aircraft
- 21%Carrier
- 17%National Airspace System
- 4%Extreme weather
58% 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 4,583 reported delay minutes here, that single category outweighs weather by 15 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 4,583 delay minutes reported on AA 1279.
Cancellations run at 2.84%, against 1.81% nationally. That is roughly one flight in 40 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. 9.2% 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 926 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
AA 1279 is not only a CMH to DFW flight. It also flew DFW to CMH (280 flights, 83.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 282 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 1279
