Just fresh from the oven. I did TXL-DUS-HKG-PVG yesterda. TXL-DUS on AB and DUS-HKG-PVG on CX. AB refused to interline my 2 suitcases because it was on 2 different PNRs. AB only allows one checked luggage and 1 cabin luggage. I had 1 cabin luggage and 2 checked suitcases. As I protested about AB's refusal to interline my 2 checked suitcases, AB check-in staff said they still would not interline (meaning I have to claim my luggage and re-check in in DUS) because interlining two different PNRs is CX's policy, not AB's. However, they did not charge my 2nd suitcase because CX allows me to bring 2 checked luggage
