How to get to Myanmar from Bulgaria
From Bulgaria you can fly to Bangkok and from there catch a connecting flight to either Mandalay or Yangon in Myanmar, or fly directly to the respective cities in Myanmar. Although the tickets in the first case might seem a little cheaper, there is a catch – the multiple entries visa for Thailand is priced at 150 Euros per person.
So my advice will be to fly directly to Myanmar or get a single entry visa for Thailand for 30 Euros, go to Bangkok, from there to Mandalay or Yangon and then come back to Bulgaria directly from Myanmar to avoid spending that much money on the expensive Thai visa.
Visa for Myanmar/Burma
You can apply fo an eVisa for Myanmar here. The price for a tourist visa is $50. The application is processed within a few days.
Sofia Bangkok flight
The cheapest tickets I have been able to find to Bangkok from Sofia are the ones offered by Qatar Airways – around 450 Euros. Of course, you need to book them a few months in advance in order to get a good deal with a layover of less than 3 hours in Doha. The total duration of the flight without the connection time is around 12 hours.
Bangkok Mandalay flight
AirAsia offer return tickets for as much as 70 Euros per person. The duration of the flight is a little less than 2 hours. The flight departs from Don Muang Airport.
How to get to Don Muang Airport in Bangkok
You can take the BTS Skytrain to Mo Chit station and from there take exit 3 and at the end take the escalator down on the right. Once down to the street, the A1 bus stop is just in front of you. The ticket for it costs 30 Baht. If you miss the bus (which happened to us), you can take a taxi. For a taxi from Mo Chit to the airport we paid 130 Baht.
