Hi. This isn't the only company I applied for, and I did use the search function. I am not decided which airline I will work for yet. Apologies in advance if I missed something in the search or if insults anybody here for any reason.

I interviewed recently and, living in NY, want to fly out of LGA or JFK. For Shuttle, I can choose the 145 out of JFK or LGA, or 170 out of just LGA. Does anybody have any advice regarding upgrade time per base, or the worth of having two types upon the eventual switch to the 170, or any other relevant points to ponder? The signing bonus is a lot more for the 145, so there's that.
