Hi,
i have a light ticket outbound to thailand business class this summer. This includes luggage for 4 people
the return is also light ticket, but premium economy. This flight starts in phuket with Malaysian airlines to KL and than with KLM back to Amsterdam.
here comes my challenge:
- klm phone support can not add luggage to the returnflight, claiming MH is the starting airline
- MH phone support can not add luggage to the returnflight, claiming it is KLM codeshare and they can not modify booking to add luggge.
- logging in with thr PNR on MH site i can see all flight details, but not select seats/ add luggage.

MH says i can buy luggage at the airport, but they can not state a price other than the excess luggage prices (to europe 44 usd per kilo),and with 4 people each having 20kg this would get ridiculous expensive

what would you advise to do?
