Best time of day to fly
On-time rate by scheduled departure hour (local time at ICT). Delays build through the day as late planes knock on, so early flights usually do best.
Last flight of the day
On ICT → IAH, each airline's last flight of the day was cancelled 1.7% of the time, against 0.9% for its earlier flights (1.9× as often). It arrived 3+ hours late 3.3% of the time (earlier flights: 1.3%). 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.

|---|---|---|---|---|---|
| United Airlines | 3:32 p.m. | 1.7% | 3.3% | 0.9% | first flight 6:30 a.m. |
