I think you have been moved to the correct forum now, FT works on the basis of your start point rather than your end point in this particular area.

There are some stickies at the top of the forum which explain the system in some detail, but the short answer to your question is that if there is a SAAver redemption availability on AA, it should also be available via BA, or rather BAEC. If you want to share the route concerned then we can give more specific advice, some routes make a lot of sense on BAEC, others make no sense at all (due to lack of availability or the route network). In essence many travellers find BAEC a useful adjunct or alternative to AA for redemption bookings.
