We will be flying from SFO to Gatwick to Edinburgh.
I assume we go through customs in Gatwick and will need to know how much time to allow between flights.
Or, if we fly from SFO to Paris to Edinbugh would we need the same amount of time between flights given that we are going from Eu to the UK.
I have seen some layovers that are only 1.5 hours which does not seem to be enough time.
Thanks...
