These figures cover 363 flights between September 2025 and August 2026. The median arrival is 10 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
AA 2621 quarter by quarter
AA 2621 did not run the same all year. Its best quarter was Jul–Sep 2026 at 91.7% on time and its weakest Oct–Dec 2025 at 76.9%, a swing of 15 points on roughly 91 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 202592 flights76.9%
- Jan–Mar 202690 flights80.0%
- Apr–Jun 202690 flights87.1%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AA 2621 did best on Thursday at 92.3% on time and worst on Monday at 74.0%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AA 2621 runs when it is late
AA 2621 often beats the schedule: 131 of 350 completed flights, 37%, arrived 15 minutes or more early. The 57 late arrivals split 25 under half an hour, 16 between 30 and 60 minutes, and 16 an hour or more.

Share of 350 completed flights by arrival against schedule.
A late pushback is often recovered here: of 53 departures that left 15 minutes late or more, 18 still arrived on time. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.
The worst days
Worst days for AA 2621
The latest arrival of the period was on 6 January 2026, 24 hours 29 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 January 2026 | 24 hours 29 minutes | Carrier |
| 26 January 2026 | 23 hours 14 minutes | Carrier |

Delay causes
Why AA 2621 runs late
Carrier accounts for 71% of the 6,119 delay minutes carriers reported here, and the remaining four split what is left.
- 71%Carrier
- 20%National Airspace System
- 5%Extreme weather
- 4%Late-arriving aircraft
The largest share of delay minutes, 71%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,350 of the 6,119 delay minutes reported here. The split is drawn from 6,119 delay minutes reported on AA 2621.
Cancellations run at 3.31%, against 1.89% nationally. That is about one flight in 30 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
Badly late arrivals are rare here: only 4.6% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 853 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.
Every one of the 363 flights under AA 2621 in the data flew MKE to DFW. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 363 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 2621
For a booking, the cancellation rate is the figure to plan around on AA 2621: 3.31% of its 363 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
