But that doesn't apply going in the other direction, does it? I'm flying JFK-CDG-LHR in a couple of weeks - don't I have to clear immigration at my first point of entry in the EU? I'm nervous because I only have 90 minutes and I'll be in the upper deck of the A380, which will take longer to disembark. I've never done 2E > 2E before, but I assumed I would need to to clear both immigration and security and I'm concerned I won't have enough time.
