Departure window
The best time of day to leave RSW in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 33 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am480 flights94.5%
- 8am–11am184 flights91.8%
- 11am–2pm567 flights83.6%
- 2pm–5pm351 flights71.3%
- 5pm–8pm416 flights61.9%
- 8pm–5am89 flights62.9%
Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 61.9% on time, against 94.5% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 567 flights scheduled in it.
Across the week, Tuesday is the strongest day at 84.4% on time and Sunday the weakest at 75.9%. 9 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at RSW in June
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 85.3% of the time; Southwest Airlines manages 74.4%. Sample sizes sit next to every figure, because a two-point gap across 492 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 515 | 85.3% | 66 min | 0.58% | A+ |
| Southwest Airlines | 492 | 74.4% | 62 min | 0.61% | C+ |
| American Airlines | 466 | 74.6% | 83 min | 2.36% | C |

| Frontier Airlinesthin sample | 68 | 80.6% | 117 min | 1.47% | B |
Delta leads Southwest by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes
What held RSW up in June
One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 32,000 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.
- 48%Late-arriving aircraft
- 31%National Airspace System
- 15%Carrier
- 6%Extreme weather
- 0%Security
48% 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 32,000 reported delay minutes here, that single category outweighs weather by 8 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 32,402 reported delay minutes.
Cancellations sit at 0.91% against a national 1.65%, which is ordinary. Diversions add another 0.48%.
8.2% of arrivals land an hour or more late, close to the national 9.7%. 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.
