and yeah i'm still a 1k if that matters, but i'm guessing that not really (except for upgrade possibilities). on a W fare if anyone's interested too. i actually bought it a few days ago and it was interesting because i distinctly remember inventory was available in S or above, and i ended up getting priced a W fare and then when i looked at my reservation it said all seat assignments were taken.
