Fit seems to be very highly dependent on if they think you're going to bail for a Legacy. I interviewed in June, and thought it went great! But I was grilled hard in the final CP interview about my other apps out to United/Delta. It really is the only thing I can think of that caused them to send me the TBNT letter.

So to any future hopefuls, make sure you think about what you'll say when they ask about other apps. I honestly don't even know what I'd say differently...
