AA 2621 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 close to two hours on average. That is a workable record, not a spotless one. That rests on 364 flights, with a median arrival 6 minutes early.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 6 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.
Schedule
When AA 2621 flies
AA 2621 flies MKE to DFW without a single fixed slot. Its most common scheduled departure was 06:20, used on 66 of 364 flights, with 07:08 (44 flights) and 06:14 (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 06:20 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 2621 runs 8 points worse at 80.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
AA 2621 quarter by quarter
AA 2621 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.1% on time and its weakest Oct–Dec 2025 at 76.9%, a swing of 10 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.

By weekday, AA 2621 did best on Thursday at 86.5% on time and worst on Monday at 69.4%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 2621 runs late
One category carries most of the weight here. Carrier accounts for 75% of the 6,860 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.
- 75%Carrier
- 20%National Airspace System
- 5%Extreme weather
- 1%Late-arriving aircraft
The largest share of delay minutes, 75%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 5,119 of the 6,860 delay minutes reported here. The split is drawn from 6,860 delay minutes reported on AA 2621.
Cancellations run at 3.57%, against 1.81% 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
5.4% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.
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. 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.
Every one of the 364 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. 364 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: 3.57% of its 364 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.
