recently booked a trip thru AA, crediting to AS (outbound BA PE, BA Y; return IB PE, AA Y) … AA PNR shows both the BA and IB PNRs

AA leg allowed MCE seat selection; IB worked fine, but BA app says I have to pay for seats on both flights

BA chat rep said he can see AS (Atmos) number, but not OWE status; his suggestion was to contact AS

“not sure why would I need to do that when I’ve never had any issues with AS status pulling through to AA for domestic flights”

long silence … “you will need to have AA change to AAdvantage number”

”that won’t work because I need to credit to AS”

c’mon, people, isn’t one of the principal goals of an “alliance” to facilitate seamless travel across all partners??

I suppose I can have AA add my AAdvantage number, but I’ll have to remember to switch it back to AS when we check in for the BA flights


grrrrrrrrrr
