Best time of day to fly out of SJT
Time of day matters more at SJT than almost anything else you control. Flights scheduled to leave at 5 a.m. arrived on time 85% of the time; at 6 p.m. it was 67%, a 18-point gap. Taken together, early departures (5–9 a.m.) ran 85% on time against 67% 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.
