A friend of mine is traveling from GV->FRA->DEL next week. She was booked on AI, but she is now rebooked on LH metal from FRA. Now will LH baggage rules apply (1 piece) or AI rules (2 pieces, combined 20 kg)? My feeling is LH one will apply, unless AI have some special note in her eticket, but I wont mind being stand corrected.
