Not sure if I should post this under BA or AA ... it's kind of a weird set of facts. I travel a lot to the UK for work and have Silver status on BA (none with AA). Whenever I fly AA, I use my BA number. I have booked a roundtrip business class ticket on AA from BOS to CUN for May with my BA number. This itinerary is not eligible for AA lounges despite the ticket class. My question is whether anyone knows whether I can access a BA lounge or AA lounge due to my Silver BA/ Sapphire OW status. Sorry if this has been asked and answered previously. I couldn't find anything on point when I searched earlier.
