There are a number of ways in which you can get to Thailand form the UK, but driving is not one of them. Many tickets for flights can be found reasonably cheap online, and you can get direct flights to Phuket or Bankok while London Heathrow tends to be main airport in the UK for Thailand departures.
Prices tend to be higher in the high-season which is between December and March and this is when many people plan their tours. Thailand is a country that’s full of low prices and bargains but flights are not necessarily part of that, and return flights from the UK can cost between £600 to £1000.
Bankok is the airport to go to if you’re staying in the city or nearby, but Phuket tends to be the airport for those planning relaxing holidays and adventure travelling with beautiful sights and surroundings nearby., Getting to Thailand is not exactly challenging, but you may arrive with jet lag, and then the difficulty of finding your hotel or hostel.
