Transiting in Beijing
Flying KA in economy from HKG to BJS and then connecting onward to YYZ on AC in business.
1) I assume KA staff would through check the luggage and issue the AC boarding pass in HKG ?
2) What would be the weight limit on check-in luggage ?
3) At BJS, given that KA and AC both operate in T3, would immigration clearance (entry and then exit) be required ? Or would go straight through airside ?
