Many years ago (in 2019) I made a trip to Germany with friends, departing by plane from London (LHR) and arriving in Munich (MUC). Munich's international airport has two terminals. For practical reasons, we took different flights. I arrived first, in Terminal 2; while my friends arrived later, in Terminal 1. Given my arrival was earlier, so I had time to cross to another terminal, we planned to meet in Terminal 1.
In hindsight, the way I should've taken to Terminal 1 should've been:
- Starting in Terminal 2, follow the signs for the exit.
- Pass immigration in Terminal 2.
- Exit the terminal building.
- Walk across the Munich Airport Center to Terminal 1.
Instead, what I did was:
- Starting in Terminal 2, follow the signs for Terminal 1.
- Board the shuttle bus for Terminal 1.
- Enter Terminal 1. I do not recall passing through any control point (security/immigration) before entering Terminal 1.
Being in an unfamiliar place, late in the day, and tired from the flight, I was on autopilot navigation to Terminal 1 and did not realise the problem until it was too late: I was in the airside departure area of Terminal 1. There wasn't an exit. After wandering around lost for what felt like forever, I was eventually able to get out with assistance from staff. When passing immigration in Terminal 1, the officers were bemused at what had happened.
My questions are:
- Should my journey from Terminal 2 to Terminal 1 have even been allowed to happen? In my experience, changing to the airside departure area of another terminal is typically only possible if you have a boarding pass for a flight connection from the other terminal. I did not have a connecting flight so would not have had a boarding pass.
- If MUC actually does allow this, why does it? Given many airports don't allow changing terminals without a boarding pass and it enabled a situation where it's not possible to exit the terminal (without special assistance), why does Munich allow for this possibility?
- If it was not supposed to be allowed, how was it allowed to happen? (There might have been some specific detail about the journey that I took which allowed it to happen but I cannot recall.)
