Same layover, different day-part
How often the first flight arrives too late to connect (45 min minimum), for one-ticket layovers of 45–80 minutes.
Delays build through the day, so an afternoon first leg eats the layover. A short connection is fine early in the morning and a gamble later on.
Mixing airlines
The table above includes two-ticket connections (marked “two tickets”), held to the 90-minute minimum. One ticket only →
Regional partners count as the airline that sells them: SkyWest flying Delta Connection is one Delta ticket.
About this data: US DOT on-time records, Aug 2025 – Jul 2026, all US airlines; regional flights count under the airline that sells them. Schedules (which flights and connections exist, and their times) are as of Jun 6 – Jul 31, 2026; seasonal flights outside that window aren’t ranked. Rebuilt monthly. JSON
