Booking a flight with a layover can slash hundreds of dollars off international airfare, but it introduces the operational risk of missed connections and stranded luggage. Here is how to navigate transit hubs like a seasoned aviator.
Understanding Minimum Connecting Times (MCT)
Every international airport publishes an official Minimum Connecting Time (MCT) agreed upon between airport authorities and airlines. If an airline sells you a single ticket with an 80-minute layover at Paris CDG, that connection meets legal MCT. However, legal MCT does not guarantee an easy transfer if your inbound flight is delayed by 25 minutes or customs lines are backed up.
Key Connection Rules
- Single Ticket vs. Split Tickets: Always book connections on a single through-ticket. If an airline causes you to miss a connection on a single booking, they are legally required to rebook you for free, provide meal vouchers, and furnish hotel accommodations. If you book separate tickets on different low-cost airlines, you assume all financial risk if flight #1 is delayed.
- Luggage Through-Checking: On standard international itineraries, your checked bag is tagged to your final destination. Crucial Exception: Arriving in the United States or Canada requires you to clear border customs and physically re-check your bags before continuing on domestic connection flights.
Aviation regulations, baggage rules, and passenger rights vary by airline, route, and country. Always verify with your airline and the relevant national aviation authority before travel.
