Hub connection rankings: where short connections hold best

Of the 31 large US hubs we track, June 2026. GateCast’s measure: the share of short connections between any two flights (whether or not on the same airline) that lost 15+ minutes; the lowest share ranks first. A ranking by a measured share, no judgement on how an airport is run.

Of the 31 large US hubs GateCast tracks · rank 1 = the lowest share of short connections that lost 15+ minutes · June 2026

Method: Pairs of flights scheduled 30 to 44 minutes apart at the same hub, whether or not on the same airline, on days both flew; lost 15+ = first flight's arrival delay minus second flight's departure delay of 15 minutes or more. This is a delay measure only - it does not mean a connection was missed.

Hubs with the same figure share a rank, shown with =, and are listed alphabetically; the next rank skips.

This is the earliest month in our figures, so there is no earlier month to compare with.

Note: This delay measure counts connections between any two airlines, whether or not on the same airline group; the Power Rankings index counts same-airline-group journeys, so the two are not comparable.

Places only; no airline is ranked.
