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 85% reliability rating vs 74% for afternoon departures.
- Compared with the next-best option (Delta 1198 on the Airbus A220-100), it arrives on time 2 points more often.
- Legroom was comparable across the flights we compared (30–31 in), so it didn't set them apart.
