one more question... after the immigration thingy, should I go to the connecting flights corridor, or just find the air train?
and in case i'm reaally, reaaaally late, and i can't find my baggage drop off, can I leave it somewhere in the T4 (before the security controls) or bring it with me till the gate? I know it might sound like a stupid question, but I saw two people do that in london a couple of years ago, I just want to be sure...
Thank to you all for the answers, you all are so helpful, I feel way less worried!
I really hope I'm gonna make it!
