No, just one booking. The direct flight to Chiang Mai was really expensive so I had to go via BKK or DMK. I remember that I wasn't sure if I had to do immigration and Bangkok, and I'm 90% certain that I did it in Chinag Mai. One time for sure I've done it there
Correct me if I'm wrong here, but if you transfer at BKK for Chiang Mai, on the same booking, you'll do immigration at Chiang Mai right? No one looks at BKK. Correct me if I'm wrong here?
you're getting some banter because you were incorrectly criticsing the OP's choice of words, and in fact it is you that got the meaning of the word wrong. Grow an extra layer of skin, or get off the internet. We've all been wrong and been mocked. It's the same in every country I've lived in. Learning to laugh at one self is important in life ...
