Departure window
The best time of day to leave RSW in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 35 points, against 15 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am432 flights92.2%
- 8am–11am324 flights90.9%
- 11am–2pm582 flights73.7%
- 2pm–5pm375 flights57.7%
- 5pm–8pm455 flights58.3%
- 8pm–5am147 flights59.6%
Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.2% of the time, against 57.7% for the afternoon window. That is 35 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 582 flights scheduled in it.
Across the week, Saturday is the strongest day at 80.9% on time and Wednesday the weakest at 67.3%. 14 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at RSW in July
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 80.2% of the time; American Airlines manages 65.0%. Sample sizes sit next to every figure, because a two-point gap across 459 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 572 | 80.2% | 91 min | 1.22% | B |

American Airlines cancels 4.8% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held RSW up in July
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 49,000 reported delay minutes.
- 39%Late-arriving aircraft
- 28%Carrier
- 26%National Airspace System
- 7%Extreme weather
- 0%Security
39% 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 49,000 reported delay minutes here, that single category outweighs weather by 5 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 48,665 reported delay minutes.
Cancellations sit at 2.46% against a national 2.45%, which is ordinary. Diversions add another 0.69%.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.0% of arrivals land a full hour or more behind schedule, against 12.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
What to do with this
Flying from RSW in July
For a July trip through RSW: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 92.2% on time, and with 11.0% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
