What is the illegal layover time?

There’s no such thing as an “illegal layover time.” The idea of a layover being illegal is a misconception. Airlines don’t get fined or penalized for offering short connections, and passengers won’t face legal repercussions for booking them. The issue isn’t about legality, but about practicality and risk.

What you should be concerned about is Minimum Connection Time (MCT). This is the shortest amount of time an airline allows for passengers to transfer between two flights at a specific airport. MCTs are set by individual airports and vary based on factors like the size of the airport, the terminals involved, and whether the transfer is domestic or international.

While airlines often sell connecting flights with layovers that meet the MCT, these tight connections can be risky. A slight delay on your inbound flight can easily cause you to miss your connection. Consider these factors:

• Airport Size: Navigating a large, sprawling airport like Chicago O’Hare or Dallas/Fort Worth with a short layover can be challenging, even for seasoned travelers.
• Terminal Changes: If your connecting flight departs from a different terminal, factor in the time required to transfer, including potential shuttle rides or long walks.
• Security Lines: Re-clearing security can eat into your layover time, especially during peak travel periods.
• International Transfers: International connections often involve immigration and customs procedures, requiring more time. Factor in potential delays and longer lines.
• Baggage Recheck: While most airlines transfer checked baggage automatically, some itineraries may require you to retrieve and recheck your bags, adding precious minutes to your transfer.

While there’s no magic number, a three-hour layover is a good rule of thumb, especially if you’re checking bags or traveling internationally. Shorter layovers might save you time on paper, but they significantly increase the risk of missing your connection and facing the potential hassle of rebooking, lost luggage, and unexpected expenses.

Instead of focusing on whether a layover is “illegal,” focus on choosing a connection that provides a realistic and comfortable buffer. A slightly longer layover offers peace of mind and allows for unexpected delays, ultimately contributing to a smoother, less stressful travel experience. Consider the value of your time and the potential cost of disruptions when booking your next trip. A little extra time can make all the difference.
