Hi,

A friend of mine is flying back home to Sweden next month. He's staying on Koh Phangan and flying from Samui to Bangkok and then Bangkok to Gothenburg via Frankfurt with Lufthansa. What kind of covid test (if any) does he need and when at the latest? He tells me that he thinks Sweden doesn't require a covid test atm but he isn't sure. Does he need ont to be let on to the flights? Does anyone know?

Thanks!
