I live in Cornwall. Having to get a pre-departure rt-Pcr sorted before March. The cheapest for next day results down here is £129!! Friggin extortion!! 🤬 🥴. It’s bloody cheaper to drive up earlier and organise a 3 hr test at Heathrow!!
Has to be a sealed route! Only certain flights from BKK to Phuket qualify for this. Maybe go back to your agent or contact Thai Air directly to see if it can be sorted? 🤷♀️
