We are taking a short trip to Croatia from London, flying out of Gatwick and back into Stanstead. Do we need tickets in advance for either train trip? Can we get them an hour or so before the trips?
neither require purchase in advance (although you will lose any discounts available in advance online) but both routes - Stansted Express from Stansted and either Gatwick Express and Southern Trains from London Victoria to Gatwick, or First Capitol Connect from London Kings Cross / Saint Pancras (and several other stops) to Gatwick DO require - upon a high fine for noncompliance - purchase prior to boarding.
Thanks. I figured we'd buy at the station.
