Posted this on the AA forum but wonder if this might be a better place:

trying to book flights from MSP to LHR using AA miles. May 24
KVS shows premium FS+ availability for 3 with AA to ORD (3087) and then BA to LHR (296).
When I search on AA.com they don't show premium availability and don't show this combination on economy at all.

If I call AA directly, do I have a chance of them finding this routing? or is this not really available for AA but for other Oneworld customers?
Any way to tell if this would be MileSaver or Anytime availability?

Side note: I know BA isn't my first choice due to fees but I already have flights booked with miles in economy that use BA on another route so a lateral change there. Still hoping for a non-BA route to open up but this is the first premium cabin availability I've seen open up on KVS and want to get it if I can.

Thanks for any advice
