Emerald benefits via AA, miles credit to AS
Any tips for I-fare Club World trip on how to get both Emerald benefits via AA status (free seat assignments, F lounge access) while crediting to AS for their crazy generous 250% earn rate? AA number on reservation now. Seats secured. Can I safely use Finnair website now to switch in AS number and then present AA status card in Apple wallet for F-lounge access (boarding pass won’t show Emerald)?
