Best time of day to fly
On-time rate by scheduled departure hour (local time at BHM). Delays build through the day as late planes knock on, so early flights usually do best.
Last flight of the day
On BHM → BNA, each airline's last flight of the day was cancelled 0.6% of the time, against 1.1% for its earlier flights, so here the last flight is actually the safer one. It arrived 3+ hours late 1.1% of the time (earlier flights: 1.1%). It matters more than the numbers suggest. Miss an earlier flight and there's another one that evening; miss the last one and you're usually waiting until morning.
| Airline | Last departure | Last: cancelled | Last: 3h+ late | Earlier: cancelled | Next morning |
|---|---|---|---|---|---|
| Southwest Airlines | 5:50 p.m. | 0.6% | 1.1% | 1.1% | first flight 6:00 a.m. |
