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.
