Why this is our top pick
- This morning flight leaves in the most reliable time of day on this route: its best departures have a 72% reliability rating vs 59% for afternoon departures.
- Delta trips we compared arrive on time 77% of the time on average, 2 points more often than United and Alaska (74%).
- Compared with the next-best option (United 2169 + United 2241 on the Boeing 737-900ER), it flies a newer plane (about 3 vs 13 years old).
- Legroom was comparable across the flights we compared (30–31 in), so it didn't set them apart.
