Vietnam adds Heathrow links

Vietnam Airlines is making a very specific bet on summer travel. From March 29, 2026, it is running three nonstop flights a week from London Heathrow to Hanoi and two a week to Ho Chi Minh City, all on Boeing 787-9 Dreamliners. That matters because this is not a vague plan to “grow capacity.” It is a dated, scheduled return of long-haul seats into a market that still has surprisingly few direct options. The surprise is how narrow that market remains. Vietnam Airlines says it is the only airline offering nonstop flights between the UK and Vietnam, and Heathrow lists its Vietnam service from Terminal 4. For travelers, that means the direct link is not one choice among many. It is the link. If you want to fly nonstop from Britain to either of Vietnam’s two biggest cities, this is the carrier doing it. That helps explain why even a five-flight weekly schedule is news. Vietnam Airlines has run stronger Heathrow frequencies in winter, with four weekly flights to Hanoi and three to Ho Chi Minh City in its Winter 2025-26 timetable, and it has already said frequencies will rise again from October 25, 2026, when the next winter schedule begins. Summer 2026 is not a dramatic expansion from nowhere. It is a seasonal reset that still preserves nonstop service to both Vietnamese gateways, instead of forcing travelers back onto one-stop itineraries through the Gulf or East Asia. Those two gateways do different jobs. Hanoi is the political capital and the northern hub. Ho Chi Minh City is the commercial engine in the south. Keeping both nonstop from Heathrow means Vietnam Airlines is not just selling Vietnam as a single destination. It is selling access to two separate halves of the country, each with its own domestic feed and onward traffic. The airline’s own UK booking pages lean into that, pitching direct Heathrow service into both cities and then connections beyond them across Vietnam and the rest of Asia. That wider network is the real point of the summer rollout. Vietnam Airlines’ route map spans Asia, Australia, Europe, and beyond, and its UK-facing sales pages are full of onward options from London via Hanoi or Ho Chi Minh City to places like Bangkok, Singapore, Seoul, Tokyo, Kuala Lumpur, and Australian cities. So the Heathrow flights are not just about London-to-Vietnam demand. They are feeder pipes into a broader regional system. The backdrop is a relationship that is getting denser, not thinner. The UK government’s latest trade factsheet says total trade in goods and services between the UK and Vietnam reached £10.4 billion in the four quarters to the end of Q3 2025, up 39.5 percent from the previous year. Air links do not rise one-for-one with trade, but they do follow the same logic. More business ties, more student movement, more tourism, more visiting friends and relatives. Airlines notice when those streams start to thicken. So this Heathrow schedule is less glamorous than it sounds and more important than it looks. It is not a new airport. It is not a new continent. It is a practical piece of network design that keeps Britain directly connected to both Hanoi and Ho Chi Minh City through the summer, using 787-9s, before the airline steps back up again on October 25, 2026.
