New Study Reveals U.S. Airports Requiring Longest Connection Times

A new study by loyalty program publication Upgraded Points looks at U.S. airports where the most and least time is needed to achieve a successful connection.
“No one wants to spend their layover sprinting to a distant gate,” said Keri Stooksbury, editor-in-chief at Upgraded Points. “Accounting for an airport’s on-time flight performance, terminal infrastructure, and traffic helps travellers better predict the time needed for transitions between flights.”
The study analyzed domestic flight data across 14 distinct factors affecting terminal navigation, focusing on the 25 most connected airports in the country, as defined by OAG. Each data point was scaled for accurate comparison, and factors were weighted based on their importance to flight schedules and terminal navigation.
Every airport received an overall score out of 50, with higher numbers indicating that travellers should allow more time for a connection. The recommended layover time for each airport is an indexed calculation derived from these total scores, using a 90-minute layover as the statistical median.
Top 10 Airports Where the Most Time Is Needed for a Layover
Texas hubs demand the longest time buffers in the country, with Houston Intercontinental and Dallas Fort Worth leading by a noticeable margin.
Major international gateways like JFK and sprawling mega-hubs like Atlanta, Denver, and Chicago O’Hare follow closely behind, indicating that sheer scale adds significant time to a layover even under perfect conditions:
- George Bush Intercontinental Airport (IAH), Houston — 2 hours, 17 minutes
- Dallas Fort Worth International Airport (DFW) — 2 hours, 16 minutes
- John F. Kennedy International Airport (JFK), New York — 2 hours, 2 minutes
- Hartsfield-Jackson International Airport (ATL), Atlanta — 1 hour, 57 minutes
- Denver International Airport (DEN) — 1 hour, 56 minutes
- Chicago O’Hare International Airport (ORD) — 1 hour, 54 minutes
- Charlotte Douglas International Airport (CLT) — 1 hour, 51 minutes
- Los Angeles International Airport (LAX) — 1 hour, 50 minutes
- Harry Reid International Airport (LAS), Las Vegas — 1 hour, 45 minutes
- Newark Liberty International Airport (EWR) — 1 hour, 39 minutes
While large hubs are well represented, airports like Las Vegas and Newark prove that long walks, complex terminal layouts, and other logistical challenges aren’t limited to the busiest airports.

The Upgraded Points study says certain hubs are engineered for efficiency, featuring compact designs, fewer terminals, and shorter walking distances to help streamline passenger transit. Even as some of these facilities handle massive daily passenger volumes, their architectural footprints offer a stark contrast to sprawling mega-hubs:
- Ronald Reagan Washington National Airport (DCA) — 50 minutes
- Chicago Midway International Airport (MDW) — 56 minutes
- Dallas Love Field (DAL), Dallas — 59 minutes
- Honolulu International Airport (HNL) — 1 hour, 5 minutes
- Detroit Metropolitan Wayne County Airport (DTW) — 1 hour, 13 minutes
