Something like that... Someone check my english if that makes sense...

Also, one generally is only able to enjoy the best benefits of being on a higher tier in any FFP if you fly that airline. So to me when choosing an(other) FFP, I wouldn't pick an airline where I could easily qualify for silver or gold, but I would never ever fly them.
