Vietnam Airlines
Vietnam Airlines, a Skytrax four-star-rated carrier, is currently the world's sole airline with direct flights from the UK to Vietnam.
There are daily flights from London Heathrow to major Vietnam hubs Hanoi and Ho Chi Minh City, and with each having a flight time of just under 13 hours, they are also Vietnam Airlines' longest routes.
I had a chance to test the business class product (with rates starting from £1,818 or $2,344.83) from London to Hanoi on the relatively new Boeing Dreamliner 787-9 plane.
Here's what to expect in business class on board Vietnam Airlines' London Heathrow to Hanoi route.
