Since our rail connection in Britain will be significantly cheaper if I book our tickets in advance, I hope to determine when I'll likely pass through passport control and customs at Gatwick Airport next month. Will experienced Gatwick travelers weigh in on this scenario? Too cautious? Not cautious enough?
My flight is scheduled to arrive at 7:10am but as recently as yesterday landed 1 hour 45 minutes late (8:55). I'm considering booking an 11 o'clock train (Great Western RR, to Reading.) No changes or cancellations are allowed. I know if all was on schedule, I could probably make a 10am train, but I am being cautious. In a worst case scenario, is it still possible to arrive Gatwick by 9:30 or 10am, clear passport/customs, take the shuttle to the south terminal, and reach the train by 11am? We are two experienced international travelers, but never through Gatwick.
