Historical statistics for January 2026, not live status or a forecast for this year’s January. For today’s conditions at RSW, see live FAA status.

RSW in January carries a cancellation problem, not just a delay problem: 4.1% of scheduled flights never operate, against 4.7% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 3,454 flights, of which United Airlines flew 600 at 86.1% on time.

United Airlines is the most reliable of the five carriers covered here at 86.1% on time across 600 flights.

RSW across all twelve months

These figures cover 3,454 departures from Southwest Florida International in January 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

January next to RSW's other months

Against RSW's own year, January ran level with the twelve-month rate of 78.1%, which makes it number eight of twelve months, best first. Cancellations are where January stands out: 4.11% of scheduled departures were called off, 2.2 times the airport's rate across the year. Either side of it, December ran 74.2% on time and February 73.8%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave RSW in January

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 22 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am567 flights91.9%
  • 8am–11am499 flights88.4%
  • 11am–2pm874 flights77.1%
  • 2pm–5pm685 flights71.0%
  • 5pm–8pm623 flights71.6%
  • 8pm–5am206 flights70.3%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 91.9% of the time, against 70.3% for the overnight window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 874 flights scheduled in it.

Across the week, Wednesday is the strongest day at 86.3% on time and Monday the weakest at 67.2%. 19 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at RSW in January

The choice of carrier is not cosmetic here. United Airlines arrives on time 86.1% of the time; JetBlue Airways manages 68.8%. Sample sizes sit next to every figure, because a two-point gap across 368 flights means less than a ten-point one.

Delay causes

What held RSW up in January

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 57,000 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.

  • Late-arriving aircraft
    51%
  • Carrier
    31%
  • National Airspace System
    14%
  • Extreme weather
    4%

51% 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 57,000 reported delay minutes here, that single category outweighs weather by 14 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 56,655 reported delay minutes.

Cancellations run at 4.11%, against 4.71% nationally. That is about one flight in 25 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.

8.3% of arrivals land an hour or more late, close to the national 7.6%. 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 a little over an hour, which a normal layover absorbs.

What to do with this

Flying from RSW in January

For a January trip through RSW: expect 78.6% on time and 4.11% cancelled, going by January 2026. The 5am–8am window was the strongest part of the day.
