As of today I’m an AY status member. I thought a minute if I should aim for Gold (rather easy with a return flight once a month including domestic connections). But then again BA Gold is rather easy to get and I’m now half-way through to life-time Gold. It is a pity BA don’t have a life-time silver. So I guess the AY silver is going to be wasted. Are there any benefits with non-OW code-share flights?
