panama and costa rica, you get out of the plane go to your connecting gate (costa rica is not a hub ..panama very much is)

mexico...weird arrangement......you go through immigration at MEX......then you do customs at your final destination


and well....there is Venezuela's method on departure (my brother told me about it)

the militars go on the plane.....doing a final 'passport check'......then if you are 'lucky' they call you up.....and you have to go down to the tarmac...........so that they go through your suitcase contents with you...in case they find anything suspicious.
