Frequently asked questions

Is it cheaper to buy a plane ticket from Seattle - Tacoma Intl. Airport (SEA) to LGW last minute?
Booking your journey from SEA to London Gatwick last minute could save you a pretty penny if you happen to find a real bargain. However, tickets usually don't come down in price closer to the departure date. If you choose to wait, flights could also be sold out or the best seats taken. If you'd rather err on the side of caution, book well ahead of when you want to leave. Note that some of the biggest deals can be found up to a year in advance. If your preferred airline hasn't released its airfares yet, check back regularly as deals are constantly updated on Expedia.

From Seattle, you can journey to London through Gatwick Airport (LGW), Heathrow Airport (LHR) and London City Airport (LCY). Research which hub is the most convenient for you before you make a decision. If you decide to land at Gatwick Airport (LGW), it's approximately 40 kilometers south of the center of the city. Use the dollars you save when booking your journey with Expedia to uncover the city's popular attractions, such as Big Ben and Buckingham Palace.
Can I change the date of my flight from Sea-Tac Airport to London Gatwick?
