Hi Ual 737-300.
I would like to give my personal comment on that. I flew last summer United Express EMB-120 ( actually it was a Skywest livery airplane ) N216SW from Fresno to LAX and it was a nice flight. The airplane tends to be a little bit noisy, but that's quite normal, its a turbo-prop, but besides that it was a nice ride, it took 60 minutes and we could see the ground from a diferent prspective. The plane was not going to high anyway! The landing was smoth but we had to brake hard before we crossed the runway. My wife noted that and a few seconds after we saw rotating a nice Alitalia MD11.
CV990, the Maserati of the skies!
