Hello. We are a couple with U. S. Passports arriving at LGW from Orlando FL via British Airlines at the South Terminal on Thursday, June 13th at 10:40am. Our next flight to Barcelona departs from LHR, not LGW, for a BA flight departing at 17:10. Does this allow us enough time to travel between the airports (via Blackberry Cars) and get through customs to catch our flight? Obviously this wasn’t a great choice on my part and I am wondering how long to expect the lines for customs will be at LHR. Thanks for your help and any tips you can provide. BTW, our cruise departs three days later.
