I'm with Matt and everyone else. Even though I can fly CO direct to many places in the U-S, I prefer to take UA and get my PremEx status (even if it means changing planes once or twice.)
And if I have to pay a few extra dollars to put a lot of miles away from special trips (Like November's Party and Paradise) then in the long run TO ME it's worth it.
While UA recently tested my loyality (read the DFW-ORE-EWR post under UNITED) it's still my preferred airline and I will alwasy go to them first for fares. CATMAN
