Minimum Connection Time (MCT) is the shortest layover an airline will sell on a connecting itinerary. It's set by each airport and varies based on whether your connection is domestic-to-domestic, domestic-to-international, or international-to-international. While airlines won't book you on a connection shorter than the MCT, that doesn't mean the official minimum is comfortable — it often assumes everything goes perfectly, with no delays, no immigration queues, and no confusion navigating a sprawling airport.
For self-booked itineraries on separate tickets, there is no MCT protection at all. If you miss your connection, you're on your own. This guide helps you understand realistic connection times at Europe's major hubs so you can plan layovers that actually work.

Official MCT ranges from 60 to 90 minutes depending on terminals. However, Heathrow's five terminals are spread across a large area, and transferring between Terminal 5 (British Airways) and Terminals 2–4 requires a bus or train. Budget at least 90 minutes for same-terminal connections and 2 hours for cross-terminal transfers. If arriving from outside the Schengen area, add time for UK immigration.
Lufthansa's main hub has an official MCT of 45 minutes for Schengen-to-Schengen connections. In practice, Frankfurt has two terminals connected by the SkyLine train (2-minute ride). Within Terminal 1, walking between gates can take 15–20 minutes through the long concourses. For non-Schengen arrivals, allow 90 minutes minimum due to passport control queues.
Schiphol is a single-terminal airport, which simplifies connections. The official MCT is 40–50 minutes for Schengen connections and 50–60 minutes for non-Schengen. However, the airport can be congested during peak hours (7–10 AM and 4–7 PM), and security re-screening for transfer passengers can add 20–30 minutes. A 90-minute layover is advisable for comfort.
CDG is notoriously complex, with three terminals and multiple satellite buildings connected by the CDGVAL automated train. Terminal changes can take 30–45 minutes. The official MCT ranges from 60 to 90 minutes, but experienced travelers recommend 2 hours for any connection involving a terminal change, and 2.5 hours if arriving from outside the EU.
Munich's efficient layout makes it one of the easiest European hubs for connections. Terminal 2 (Lufthansa/Star Alliance) has an MCT of just 30 minutes for Schengen connections. The Munich Airport Center connects Terminals 1 and 2 with a short walk. Budget 60 minutes for cross-terminal connections and 90 minutes for non-Schengen arrivals.
The new Istanbul Airport is enormous but well-designed for transfers. Turkish Airlines connections have an MCT of 60–75 minutes. The airport's transfer desks are efficient, but the sheer distances between gates can mean 15–20 minute walks. For international-to-international connections, 90 minutes is comfortable; 2 hours if you want to visit the lounge.
If you're stuck with a short layover, several strategies can help. Sit near the front of the plane to deplane quickly. Have your boarding pass for the connecting flight ready (downloaded on your phone or printed). Know your departure gate before landing — check the airline app during descent. Skip checked luggage if possible, as bag transfers are a common cause of missed connections.
For Schengen-to-Schengen connections, you won't need to clear passport control, which saves significant time. However, Schengen-to-non-Schengen or the reverse always requires immigration, adding 10–40 minutes depending on queues and staffing. Automated e-gates (available to EU/EEA passport holders) can speed this up considerably.
If both flights are on the same booking (PNR), the airline is responsible for rebooking you at no cost. Under EU regulations, if you arrive at your final destination more than 3 hours late, you may also be entitled to compensation under EU 261. If your flights are on separate bookings, you have no protection — the second airline has no obligation to rebook you or wait. This is why booking connections on a single ticket is strongly recommended, even if slightly more expensive.
Rather than stressing over tight connections, consider intentionally booking longer layovers and exploring the connecting city. Many European airports have excellent public transit to the city center — Amsterdam Schiphol to central Amsterdam takes 15 minutes by train, Munich Airport to the city center takes 40 minutes by S-Bahn. A 6–8 hour layover gives you time for a meal and a walk through the city before your onward flight.

For same-terminal Schengen connections, 60–75 minutes is generally safe. For cross-terminal or non-Schengen connections, aim for 90 minutes to 2 hours. At complex airports like Paris CDG, 2 hours minimum is advisable for any terminal change.
If both flights are on the same booking, the airline must rebook you on the next available flight at no charge. You may also be entitled to EU 261 compensation if you arrive 3+ hours late. If the flights are on separate tickets, you have no protection and will need to buy a new ticket.
It depends on the airport. At single-terminal airports like Amsterdam Schiphol, transfer passengers usually go through a dedicated security screening. At multi-terminal airports, you may need to exit and re-enter security. Schengen-to-Schengen transfers typically skip immigration but not security.
Munich (MUC) is widely considered the easiest major European hub for connections, with short walking distances, efficient signage, and MCTs as low as 30 minutes. Helsinki (HEL) is another excellent choice for compact layout and fast transfers.
Only if the savings are significant and the layover is long enough (4+ hours) to absorb potential delays. Separate tickets mean the airline has no obligation to help if you miss a connection. For tight connections, always book on a single itinerary.
