Frequently asked questions

Is it cheaper to buy a plane ticket from San Sebastian Airport (EAS) to LHR last minute?
Booking your trip from San Sebastian Airport (EAS) to London Heathrow last minute could save you a pretty penny if you’re lucky to find a real steal. However, fares generally don’t get cheaper closer to the departure date. If you wait around, flights could also be sold out or the best seats taken (because who wants the middle seat?). If you’d rather not hedge your bets, book well in advance of when you want to leave. It’s worth noting that some of the best deals can be found up to a year in advance. If your favorite airline hasn’t released its fares yet, check back regularly as offers are updated on Expedia all the time.
