MKE across all twelve months

These figures cover 2,588 departures from Milwaukee Mitchell International in April 2026. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

April next to MKE's other months

Against MKE's own year, April ran 3 points better than the twelve-month rate of 78.1%, which makes it number three of twelve months, best first. Either side of it, March ran 74.3% on time and May 80.6%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave MKE in April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 19 points, against 13 points between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.1% of the time, against 69.8% for the evening window. That is 19 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 701 flights scheduled in it.

Across the week, Wednesday is the strongest day at 83.3% on time and Thursday the weakest at 78.4%, a spread of 5 points.

Carrier by carrier

Which airlines ran best at MKE in April

The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 83.9% of the time; SkyWest Airlines manages 70.5%. Sample sizes sit next to every figure, because a two-point gap across 744 flights means less than a ten-point one.

Delay causes

What held MKE up in April

Carrier accounts for 43% of the 42,000 delay minutes carriers reported here, and the remaining four split what is left.

The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 18,000 of the 42,000 delay minutes reported here. The split is drawn from 42,091 reported delay minutes.

Cancellations sit at 2.20% against a national 0.90%, which is ordinary. Diversions add another 0.08%.

7.3% of arrivals land an hour or more late, close to the national 6.4%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
