MDW in February lands a B+, about a point better than the national rate of 80.2%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 4,537 flights, with a median arrival 8 minutes early.

MDW across all twelve months

These figures cover 4,537 departures from Chicago Midway International in February 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

February next to MDW's other months

Against MDW's own year, February ran 7 points better than the twelve-month rate of 75.1%, which makes it number two of twelve months, best first. Either side of it, January ran 80.9% on time and March 68.7%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave MDW in February

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am533 flights89.5%
  • 8am–11am1,253 flights86.6%
  • 11am–2pm695 flights81.7%
  • 2pm–5pm638 flights77.5%
  • 5pm–8pm856 flights75.4%
  • 8pm–5am562 flights76.9%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.5% of the time, against 75.4% for the evening window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 1,253 flights scheduled in it.

Across the week, Tuesday is the strongest day at 88.8% on time and Friday the weakest at 73.2%. 16 points is a smaller lever than departure hour, but it is free.

Delay causes

What held MDW up in February

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 38,000 reported delay minutes.

  • Late-arriving aircraft
    37%
  • Carrier
    37%
  • National Airspace System
    24%
  • Extreme weather
    2%
  • Security
    0%

37% 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 38,000 reported delay minutes here, that single category outweighs weather by 24 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 38,273 reported delay minutes.

Cancellations sit at 0.90% against a national 2.25%, which is ordinary. Diversions add another 0.20%.

Badly late arrivals are rare here: only 3.7% land an hour or more behind schedule, against 6.5% 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.

What to do with this

Flying from MDW in February

For a February trip through MDW: this is one of the better months to be flying from here, 81.6% on time with 0.90% cancelled. That is a base rate for the month as a whole; a single storm can still spoil a particular day.
