Frequently asked questions

Is it cheaper to buy a plane ticket from BRU to LGW last minute?
Being a spontaneous soul is a rewarding way to travel around, but it’s not always the wisest method to land a cheap airfare. Consider booking your Brussels - National Airport (BRU) to Gatwick Airport (LGW) journey in advance instead of leaving it to the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. We recommend saving that spontaneity for when you arrive at your destination!
What airports do you fly into for London from Brussels?
From Brussels, you can get to London via Gatwick Airport (LGW), Heathrow Airport (LHR) and London City Airport (LCY). It’s a good idea to check which terminal is best for you before you make a decision. If you pick Gatwick Airport (LGW), it’s around 25 mi south of the city center. Use the cash you save when booking your airfare with Expedia to visit the city’s popular attractions, such as Big Ben and Buckingham Palace.
Can I change the date of my flight from BRU to London Gatwick?
Quickly and easily make changes to your Brussels Airport to LGW journey by logging in to the Expedia Trips portal. But before you make any amendments, check out the fare conditions in your itinerary to see what the airline will allow you to do and if fees apply for changes.

You can also check out our Customer Service portal for more information and to chat with our Virtual Agent.
