Just booked K6 (Cambodia Angkor Air) BKK-REP departing on a Sat morning in Nov. Departure from BKK is 10.25.

Was originally thinking that I will fly SIN-BKK Fri night, but can see a Sat morning flight would be an option.

I am looking at the following for Sat morning:
- Tiger SIN-BKK arr. 08.30
- Jetstar arr. 08.35

I have done airside connections on separate tickets before at BKK, but not sure whether K6 flights would work for this. I don't need a visa for Thailand if need to go landside.

Any thoughts on the level of risk with this connection?

Do K6 facilitate airside check-in at BKK?

Many thanks!
