Depends on where to fly and where from. From Moscow, direct flights to Bangkok are made in approximately 8 hours 50 minutes - 9 hours 20 minutes. Direct flights to Phuket reach 9-9.5 hours. The same Phuket can be reached from Bangkok, then the domestic flight will take about 1, 5 hours, totaling an 11-hour flight. To Samui - also no less than 10-11 hours in the air: to Bangkok and then the domestic flight (1, 5 hours). But to Pattaya, for example, an internal flight is not necessary - only 2, 5 hours by bus separate the popular coast from the capital of Thailand. So this resort will have to fly to this resort only 9 hours
