I had my first experience flying with Frontier Airlines today, and I have to say it was most pleasant. Of course, it helped matters that my second flight of the day from Denver to St. Louis was probably 50% empty and the plane was a practically brand-new Airbus A318—it certainly beat the crap out of being squished in a United Express regional jet with drunken yahoos sitting in the row behind me, even accounting for the $29 upgrade to Economy Plus so I could actually use my tray table.
