On that trip I used both Gatwick and Heathrow airports, as I stayed in London a few days then went on to Madeira, Portugal via Gatwick. When I first arrived from the US, I came into London Gatwick around 8am. The line for customs was miles long and it took about 30 minutes to get through.But when I came into Gatwick around 5pm from Madeira it was a ghost town. I kid you not, there wasn't a soul in the line, and the baggage re-claim area was dead quiet.ast Tuesday, it took 45 minutes to get to an immigration officer through a queue line that would do Disneyland proud...the immigration inspection took oh about 15 seconds, she looked at my landing card, my passport, asked how long I would be in the UK, stamped my passport and said, off you go..
If you're checking bags,you generally need to have checked in and given your bag to the airline at least 30 minutes before departure. Depending on the airline, some destinations may require checking baggage more than 30 minutes before the flight.For example, if you are flying to New York or Los Angeles on American Airlines, your baggage cutoff time is 45 minutes before departure.his allows ample time for you to check in for your flight, check baggage and go through security screening. This recommendation refers to the time you actually arrive in the airport terminal, though. If you need to park, return a rental car or ride a shuttle from the airport parking area, include time for that.
