Our international flight lands at BKK airport late at night, then in the morning we have an early flight with Thai Air (we are not arriving to BKK onThai Air).
We plan to have our luggage checked all the way through to Krabi, our final destination.

In the past when we flew to Bkk and then took first flight in the morning to Chiang Mai, we just stayed few hours at the transit and cleared the immigration in Chiang Mai.
Can we stay in BKK transit and clear the immigration in Krabi?
thank you
