I'm looking to head west for a ski trip from Dec. 14-19. Three airlines offer service from STL-DEN nonstop. F9, AA, and UA. All three depart at identical times in the morning. UA and AA's flights are a little less so I'm trying to decide between the two. The AA flights are on RJs and UA is more than likely going to be a 733 or 735.
Having said that, what are your opinions. I've flown F9 and TSA on this route. I've never been on UA. Do the 737s have ch. 9? I'm a pilot so that would probably make the flight more enjoyable. At the same time, I find the ERJ to be very comfortable as I'm not very tall. I'm torn between the two so I thought I'd see what you seasoned veterans of airline travel have to say. Thanks for the input!
