Best time of day to fly out of EUG
Time of day matters more at EUG than almost anything else you control. Flights scheduled to leave at 5 a.m. arrived on time 93% of the time; at 6 p.m. it was 57%, a 36-point gap. Taken together, early departures (5–9 a.m.) ran 91% 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 1.6% of the time, against 0.7% overall.
Hour × month
Combine the two and the spread is wider still. The most reliable combination at EUG was a 5 a.m. departure in July (94% on time); the least, 6 p.m. in June (55%). If you can only move one thing, move the hour. Departure hour usually shifts the odds more than the month does.

Why flights are late at EUG
Airlines report a cause for every flight that arrives 15 or more minutes late. At EUG, 36% of delay minutes came from the airlines themselves: crew, maintenance, cleaning, fueling and baggage. Next is late-arriving aircraft at 34%. Of the 71 cancellations, 38% were blamed on weather, so most were within the airlines’ control or the air traffic system’s.
The average taxi from gate to takeoff is 16 minutes, about typical for a large U.S. airport.
Month by month
Over the latest 12 months 82% of EUG departures were on time, against 81% in the 12 months before: essentially unchanged. The best recent month was February 2026 (88%); the worst, August 2026 (72%).
Worst cancellation days
The worst single day in the past year was Wednesday, Jan 14, 2026, when 18% of 22 scheduled departures were cancelled.

Tips for flying out of EUG

- Choosing between airlines? Delta Air Lines has the better record here.
- Delayed already? Most delays at EUG come from the airlines themselves. If your inbound plane is late, your flight will be too, whatever the board says.
