I've read through the Wiki and I think I'm ok, but want to confirm.

I'm planning to book a couple RT tickets. The first would be LAX to CSX on Hainan. The next would be CSX to DMK/BKK on Air Asia. My question is with separate itineraries, would I still be good for the transit visa?

Essentially my full trip looks like LAX>CSX>DMK/BKK>CSX>LAX just on 2 different itineraries/airlines.

Thank you!
