My flight was Milan Malpensa-Bangkok Suvarnabhumi. At the airport you can easily find places where you can exchange money. I took a taxi from the airport to the city because it was my first time there and I didn't know about the "skyline" that links the entire city.
I found Bangkok a very easy and safe city where you can walk around and take public transportation without any problem. You can taste any food you want because is very international
