I took my very first flight on F9 a couple of weeks ago. Even with less than 7 days advance notice, I was able to buy a $148 roundtrip to LA (with all taxes included). Mind you, this is a direct service to LA from MSP!! NW did not match that fare... which in a sense I can understand will be damaging to their bottom line. On the other hand, I thought NW will be ruthless in driving out competition immediately.

Anyway, F9's service was great. Both ground and air staffs were friendly and courteous. Although I didn't pay to watch their DirectTV program, I thought their IFE was fantastic for a 3-4 hours flight. I noticed there weren't any major disruptions with the broadcast as well. Totally worth the $5, rather than doing nothing but staring at other people or trying hard to sleep.

Meals were exceptional by coach class standard. Their Thai Chicken Wrap was pretty good!
Speaking of coach, their seats were comfortable. I didn't measure, but their seat pitch was adequate, perhaps better than most of the major airlines (with the exception of AA's MRTC).

In all, I would definitely fly with them again. ^ ^ Their passenger load was better than I expected. Hopefully F9 can make some money to keep this route alive. This will definitely benefit MSP travelers going to La-La Land.

BTW, I noticed their fares are usually cheaper on their own website, than their published fares on other third-party websites like Travelocity or Expedia.
