LAS to EWR questions
- What time of day is best to fly LAS to EWR?
- Before 9 AM: 90% of flights arrived on time, against 71% for departures noon to 3 PM. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
- Which airline is most on time from LAS to EWR?
- United, with a season-adjusted 81% chance of operating and arriving on time over 2,464 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.

- July (63% on time); the best was January (87%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
