You’re really spoilt for choice with flights from London to Vietnam, although unfortunately you won’t be able to fly direct. The quickest flights make one stop en route and take between 15h 30min and 16h 15min. Turkish Airlines flies the fastest of these – departing from Heathrow Airport (LHR) and Gatwick Airport (LGW), stopping at Istanbul Airport (IST). Emirates is the other airline to choose for the shortest travel time, leaving from Heathrow and making a stopover at Dubai International Airport (DXB). All of these flights land at Ho Chi Minh City Airport (SGN). Emirates also flies the majority of the other London to Vietnam flights, taking anywhere between 18 and 30 hours. 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.

Question 17

What are the benefits of the different airports in London and Vietnam?

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.

Question 18

What is the best way to get in and out of airports in London and Vietnam?

Accepted Answer

You’ll mainly depart from Heathrow or Gatwick on flights from London to Vietnam. The best way to reach Heathrow is to catch a Heathrow Express train from Paddington Station. There are four an hour and they only take about 15 min. To get to Gatwick, hop onto a Southern Service train. They leave every 15 min from Victoria Train Station, taking roughly 30 minutes. Less frequent miscellaneous flights leave from all other London airports. For Stansted (STN) take the Stansted Express train (a roughly 50-minute trip), for Luton (LTN) take a Thameslink train (about 40 minutes), and for London City Airport (LCY) catch a DLR train (about 20 minutes). Arrival airports are pretty equally split between Ho Chi Minh and Hanoi. To get to their respective city centres, the Line 49 bus from Ho Chi Minh Airport takes about 10 minutes, and a Transerco Express bus will get you to central Hanoi in about 40 minutes.

Which cities can you get to from Vietnam airports?

This is very much a tale of two cities, in that Hanoi and Ho Chi Minh City are in opposite regions of the country and provide access to entirely different urban areas in their respective regions. From Ho Chi Minh City Airport, you can reach the coastal town of Vũng Tàu by bus in about three hours, or by hire car or taxi in about 1h 30min. Cần Thơ is a bit further inland to the west, taking just under five hours on the Line 119 bus. You can drive there in just over 2h 20min. The nearest major city to Hanoi is Thái Nguyên. It will only take you about 45 minutes to drive there, while the bus route takes about four hours due to numerous stops. You can also head to Haiphong, on the estuary of the Cam River.
