You can find the terminal number on your e-mail confirmation when you first book a flight. The gate number is typically offered when you check in for your flight online or in person at the airport. You can also find your gate number on the monitors at the airport that show information about departure and arrival times.

Finding your terminal information in 2026 is most easily done through your airline's mobile app or your digital boarding pass. When you check in for your flight—usually 24 hours before departure—the app will display your departure terminal and gate number (though the gate is subject to change). You can also find this info in your email confirmation or by searching your flight number (e.g., "AA123") directly on Google. Most major airports also have dedicated websites with real-time "Flight Status" boards that list terminals for all arriving and departing carriers. If you are already at the airport, look for large digital monitors near the entrances and in the check-in halls. For those using ride-sharing services like Uber or Lyft, the app will often prompt you to select your terminal based on your airline as you approach the airport. It is important to verify your terminal before you arrive, especially at large hubs like Heathrow or JFK, where terminals can be miles apart and may require a train or shuttle transfer to reach.
