What if my gate changes after I have already walked to the original one?

This happens frequently. Check departure screens every 20-30 minutes, especially if you are early. If your gate changes, head to the new one immediately. Airlines announce changes at the gate, but you may not hear them if you are in a shop or bathroom.

Do I need to pick up my luggage during a terminal change?

Almost never if you are on a single ticket or codeshare connection. The airline transfers your bags. Exception: some US airports require you to collect and re-check bags on international-to-domestic connections, even with a single ticket. Your boarding pass or a gate agent will tell you.

How do I know if I have enough time for a terminal change?

Minimum connection times (MCT) set by airports account for terminal changes. If the airline sold you the ticket, the layover meets MCT. Tight connections of 60 minutes or less mean you walk fast and skip browsing shops. Under 45 minutes at a large multi-terminal airport is risky.

What if I exit security by mistake during a terminal change?

You must re-clear security, which can take 20-45 minutes depending on the airport. If you realize you exited, turn around immediately. Some airports have 'wrong-way' checkpoints to get back in faster, but not all. This is the number one reason people miss connections.

Can I leave the airport during a long layover if I have a terminal change on my return?

Yes, but you will re-enter through the main terminal, clear security, and then navigate to your departure terminal. Add at least 2 hours to your timeline for this. Ensure your layover country allows you to enter—some transit visas only cover airside stays.

How to Handle Terminal Changes During Layovers

Check your connection gate immediately after landing, follow airport signage for terminal transfers, and allow at least 15 minutes for walking between gates in the same terminal or 30-45 minutes for different terminals. Most airports provide free shuttle trains or buses between terminals, and your boarding pass will show your departure gate and terminal.

Check your connecting gate as soon as you land. Look at departure screens in your arrival terminal or check your airline's app. Gates change frequently. Do not assume the gate printed on your original boarding pass is still correct. Write down or screenshot the current gate number and terminal.
Identify if you need to change terminals. Your boarding pass shows your departure terminal. If it differs from where you landed, you need a terminal transfer. Most large airports have terminals labeled with letters (A, B, C) or numbers (1, 2, 3). Same terminal? Just walk to your new gate. Different terminal? Follow signage for inter-terminal transport.
Follow signage for terminal transfers. Look for overhead signs saying 'Connecting Flights,' 'Terminal Transfer,' or your specific terminal letter/number. Most airports funnel connecting passengers toward transfer points. If you see 'Exit' or 'Ground Transportation,' you are going the wrong way—those lead outside security.
Use the airport's inter-terminal transport. Large airports provide free shuttles: trains (most common at major hubs), buses (older airports), or moving walkways (newer designs). Trains run every 2-5 minutes. Buses can take 10-15 minutes between stops. Follow signs to the platform or bus stop. Stay inside security—do not exit and re-enter unless absolutely necessary.
Re-check departure screens at your new terminal. Even if you confirmed your gate earlier, check again when you arrive at the new terminal. Gates change up until boarding. Locate your flight on the departure board and head to that gate.
Account for security re-screening if required. Some airports (notably in the US for international-to-domestic connections, or Schengen-to-non-Schengen in Europe) require you to re-clear security. This can add 15-30 minutes. If you exit the secure area or see a security checkpoint, you must go through it.
