Eva Air will resume flights from Heathrow to Bangkok from July.
The first flight will leave on July 3, with the airline operating three flights a week from then on, departing on Tuesdays, Fridays and Sundays.
July 3 will be the first time Eva Air has flown to Bangkok since the pandemic struck more than two years ago.

Sarah Wu, general manager of Eva Air’s London office, said: “We are delighted to announce that our flights to Bangkok will start again from July.
“We would like to thank all our partners for their support and are very much looking forward to welcoming our passengers back to Thailand again.”
The announcement comes two days before Thailand drops its Covid test entry requirement for vaccinated visitors in order to enter the country.
From May 1, vaccinated travellers will no longer be required to show proof of a pre-arrival negative PCR test or undergo a test upon arrival.
However, they will still be required to register for a Thailand Pass with a Covid vaccination certificate and an insurance policy with coverage of at least $10,000, reduced from $20,000.
Once they have arrived in Thailand they will be free to go anywhere in the country.
International travellers who are unvaccinated or not fully vaccinated will also no longer be required to show proof of a pre-arrival negative PCR test or undergo an arrival test.
However, they must quarantine for five days on arrival and undergo a PCR test on the fifth day.
