Frequently Asked Questions
What is the minimum layover time for a domestic connection?
For domestic connections in the US, 45-60 minutes is the minimum at most airports. Larger hubs like ATL, ORD, or DFW may need 60-90 minutes. Airlines typically won't sell connections shorter than their minimum connection time (MCT).
What is the minimum layover time for international flights?
International connections typically require 90-180 minutes minimum. You'll need time for immigration, customs, security re-screening, and potentially re-checking bags. At large international hubs, 2-3 hours is recommended.
What should I do during a long layover?
For 2-4 hour layovers: eat, shop, use a lounge, or rest. For 4-8 hours: consider an airport day-pass lounge, sleep pods, or airport tours. For 8+ hours: explore the city if you have visa-free entry. Many airports offer free city transit tours for long layovers.
