I've only ever had one check in staff member not take it. And I was able to hand it in at the gate, like several other people seemed to be doing. And this was on AY. If you get back to your home, and you still have it, and you need to re-enter soon, I was always told that the embassy/consulate can take care of it with a minimum of fuss.
