But you don't. You check in Terminal 5, you go to one of 3 different concourses. You check in Terminal 4, you go to one of 2 different concourses, one of which is shared with Terminal 5 and better connected to Terminal 4. You check in Terminal 4, you go to one of 2 different concourses. You check in Terminal 1, you go to... something that used to be 7 different concourses thought up back in the 60s, but can at very least be separated into Schengen and non-Schengen gates.
