I have an upcoming itinerary that takes us LGA->YYZ on AC, then YYZ->TPE->BKK on EVA, then BKK->CMB on TG. The itinerary is booked as a single Star Alliance award under one PNR. I have long layovers in TPE and BKK (a full day in BKK) and would rather be without the large carry-on backpacks the family will be using. Is it possible to check bags for this entire itinerary in either LGA or YYZ? If so, is it likely that the bags will arrive with us in CMB?
