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 26% for midday departures.
- Compared with the next-best option (Delta 1163 on the Airbus A319 or A321), it flies a newer plane (about 2 vs 10 years old).
- 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.

Historical odds, not a guarantee. Built from the US DOT Bureau of Transportation Statistics on-time reports (Jun 2025 to May 2026), FAA ground stop and delay program advisories, and 20 years of airport weather observations. Covers US airlines that report to the DOT; schedules are flights operated recently, so confirm times when you book. ATIS Alerts is not affiliated with any airline. Fares are what Aviasales travelers saw in recent searches (USD, one way, 1 adult), not live quotes; the partner site shows the current price.
