Accepted Answer

Given that both Heathrow and Gatwick are extremely busy international airports servicing most continents, they have world-class passenger facilities available for flights from London to Vietnam. Both offer comprehensive limited mobility assistance, and staff on hand to assist those with hidden disabilities. Children’s play areas are a boon for parents waiting for international flights, and both airports have generously large duty-free areas. Restaurants, pubs, coffee shops and fast food kiosks are plentiful throughout both airports. To split the difference, if you’re coming from the western side of London, book your return or one-way flights from London to Vietnam out of Heathrow, and if you’re coming up from the south of England, fly from Gatwick. The same situation holds in Vietnam – both airports have all the international traveller facilities you need, and the main difference between them is that Hanoi is in the northern region of the country, while Ho Chi Minh City is far down south, and closer to the coast.

Emirates is the other airline to choose for the shortest travel time, leaving from Heathrow and making a stopover at Dubai International Airport (DXB).

They land at both SGN and Hanoi Noibai Airport (HAN). Other airlines fly this route in combination, such as KLM and Thai Airways, Wizz Air and Turkish Airlines, and Ryanair with Thai Airways, the latter also offering comparatively cheap flights from London to Vietnam.
