Best time of day to fly out of TLH

Time of day matters more at TLH than almost anything else you control. Flights scheduled to leave at 6 a.m. arrived on time 88% of the time; at 6 p.m. it was 66%, a 23-point gap. Taken together, early departures (5–9 a.m.) ran 88% on time against 72% for the evening bank (5–10 p.m.). Early planes usually start the day at the airport, so they haven't had a chance to pick up delays elsewhere. By evening a late inbound aircraft, a crew running out of duty hours or an afternoon thunderstorm can push one late flight into the next. Cancellations cluster too: 6 p.m. departures were cancelled 4.4% of the time, against 1.9% overall.

Hour × month

Airlines at TLH

American Airlines runs 65% of departures from TLH, so TLH is effectively its hub. When American Airlines has a bad day, so does the airport. Among airlines with at least 1,000 departures here, Delta Air Lines was the most reliable (84% on time) and American Airlines the least (79%), a 5-point difference. On a route where both fly, that difference is worth more than a small fare gap.

Why flights are late at TLH

Airlines report a cause for every flight that arrives 15 or more minutes late. At TLH, 45% of delay minutes came from late-arriving aircraft: the plane showed up late from its previous flight, so the delay started somewhere else. Next is the airlines themselves at 37%. That's why the first flight of the morning is the safest bet: it has no earlier flight to inherit a delay from. Of the 127 cancellations, 64% were blamed on weather.

Worst cancellation days

The worst single day in the past year was Sunday, Jan 25, 2026, when 59% of 17 scheduled departures were cancelled. Days like that are usually a major storm, a system outage or a holiday peak hitting bad weather. No average predicts them, so on a stormy forecast, check your airline's travel waivers.

Last flights of the day

The last flight of the day is a different bet. Across routes from TLH, each airline's final departure was cancelled 2.9% of the time, against 1.3% for its earlier flights (2.2× as often). Late in the day crews run short on duty hours, aircraft arrive late from elsewhere, and with no later flight to fold passengers into, cancelling is easier for the airline. 1.8% of last flights landed 3+ hours late. The riskiest last flight out was American Airlines to Dallas (6.3% cancelled).
