Jaysit: Your two experiences of EWR wrt customs
and immigration taking 10 min can only be possible, if you were in FC. Having done EWR internationally many times, I can say only a few times on a 1/3 full flight from carribean trip did we see that kind of a speed
Cyrus: Why is customs an issue ? Do you have many checked baggages ? I have only once had a customs check coming back from SDQ - They were checking
nearly everyone on that flight
If there are two three international flights bunched up together, and your plane was last in the bunch, no matter what you are SOL. In those cases JFK handles that pressure better than EWR.
