I just got a really attractive USD 5XX Business Class deal ex-CMB to CAI return. I'll be transiting through CMB, and I'll have no check-in luggage. My flight arrives at 16:05 by AI flight and my QR flight leaves at 21:20.

I'd like to check-in online beforehand and have a printed boarding pass so that I don't have to clear immigrations. Wondering if this is possible.

Sometimes, airports don't accept self-printed boarding passes and require to have them re-issued at airport check-in counter (i.e. CAI). Hope that's not the case at CMB (unless if transit counter can do this work for non-UL airlines).

I apologize if the same topic has been brought already.
