Since I'm a worrier and a planner (this is probably a simple question): I have a Star Alliance award ticket to Bangkok in November, and I'm wondering how check-in and bags will be handled. On the same ticket, I fly: United from BWI to SFO Asiana from SFO to ICN, ICN to BKK On the way back I fly: Thai Airways from BKK to NRT ANA from NRT to ORD United from ORD to BWI When I check in at BWI, will I get my tickets for all my flights to BKK? If I check a bag, will it be checked all the way through? Same applies on the way back, I guess. Thanks!
