5 busiest U.S. airport hubs by 2025 passenger boardings
The five leading U.S. commercial airports in the FAA’s preliminary calendar-year 2025 enplanement ranking, with connection, ground-transport and disruption checks.
YOUR CHECKLIST
What’s worth comparing first?
Your family, budget, and daily life come first. One great statewide number can’t make the whole decision for you.
Network usefulness
A busy airport may offer more nonstop options but can still be inconvenient for your routes.
Connection design
Terminal layout, minimum connection time and airline location matter.
Ground trip
Add rail, tolls, parking, rental-car transfer and peak traffic to the airfare.
A GOOD PLACE TO START
States and cities worth a closer look.
This isn’t a one-size-fits-all ranking. We’ll show you what looks promising—and what you should double-check.
