I'm currently a "short stroke-high RPM" flyer primarily between Colorado and SoCal and pretty much on UA these days. Lots of segments, not so many miles.
I'd be interested to read others' opinions on F9 and what to expect if I were to switch. Of interest are things like customer service, IRROPS, how delays/cancellations are handled and how often they occur, frequency and quality (whatever that is) of promotions, discounts, sales, award tickets and other perks, and so forth.
Asking for opinions on FT always gives me pause - we seem to have a healthy share of them

- but bring 'em on!
Thanks,
