Hi,
I'm new to this forum, so excuse me if i use the wrong language here.

I am *A Gold on Turkish Airlines. I fly mostly from Tel Aviv to West Africa (every month) and regularly to Western Europe, and maybe 3 or 4 times a year to NYC.

On Turkish you only get upgrade vouchers if you are Elite plus, even though Elite is gold status. It seems that on some of the other *A airlines you get upgrade vouchers as soon as you are gold. Would it be worth my while to get a different *A FFP, and start accumulating miles there? Can i use my Turkish card to get into the lounge but get the points on my other card?

I've only ever received an upgrade on Turkish once, and never on Luftansa, even though i fly them a lot.

Would appreciate any help that anyone can give me.
