Being in an alliance clearly makes a difference. The memsahib just managed to through-check from BA LGW-AMS onto CX AMS-HKG – although the way she described it was “Checkin was abysmal he barely lifted his head yawned openly and grunted in responses (??) but I did manage to get bag checked all the way thru despite it not being on same ticket so at least that is something !”
BA service does seem to be falling short in this respect, whether or not the bags get checked through!
Fortunately, just to let you all know, i did manage to do the necessary in BKK to retrieve my bags and re-check, although the immigration officer did seem a bit nonplussed when she asked which hotel I was staying in and I said I was only arriving in order to check in again… !!
