Actually, i tried SQ,CX,CA,CI,MH etc.... one baggage tag max. for 3 flights. more than that system will print out another baggage tag... However, some of the airport using RFID and the baggage system will confuse 2 bag tag's luggage. then your baggage will auto send to problem area in the basement.... if you are lucky, will have staff to pick up your luggage from problem area. Otherwsie, your baggage will still there until someone comes.....
