Hi. I will be flying into BKK from Birmingham International Airport in September. I am flying with Emirates. Our flight lands at BKK at 19:20 and from there I will be heading to Koh Samui, flying with Bangkok Airways. My flight to Koh Samui departs at 21:00. I am abit worried about the amount of time it'll take to get through customs, immigration, collect baggage and check in to my flight to Koh Samui. Any tips? Thanks.
