BAEC Status and upgrades with other OW carriers
I'll soon be relocating to Florida and while I will still make return trip back to a UK regional airport at least twice a year I do also intend to do a lot of traveling within the US.
My question is, from a FFP point of view, am I better off sticking with BA (I will fly the minimum number of flights in a given year to be eligible for status) or should I move to the AA program?
I gather that sticking with BA would give me lounge access on domestic AA flights as long as I have BA silver or above, whereas I wouldn't with AA status even when flying first on domestic AA flights.
From an upgrade point of view are OW status holders treated equally when it comes to upgrades or do AA members get preferential treatment over other OW status holders? I know OpUps are rare but I've heard they are more common in the US than they are with BA
