Why this is our top pick
- This morning flight leaves in the most reliable time of day on this route: its best departures have an 84% reliability rating vs 71% for overnight departures.
- Delta trips we compared arrive on time 83% of the time on average, 9 points more often than Southwest, United and American (74%).
- Compared with the next-best option (Delta 327 on the Airbus A350-900), it arrives on time 6 points more often.
- Legroom was comparable across the flights we compared (30–31 in), so it didn't set them apart.
Aircraft and legroom reflect the planes each flight has flown recently. Airlines can swap planes and seat maps change, so check the airline’s seat map when you book.
