I have an award booking SIN-FRA-JFK SQ26. I will need to get from BKK-SIN earlier in the day. If I book a ticket with SQ, which I plan to do, I have two questions.
1 - In BKK will they check my bags all the way through to JFK?
2 - Can they check me in at BKK for SQ 26 or am I going have to go airside in SIN and then check back in.

Thanks
