Other than previously booked flights, I've dropped UA going forward. I'm also noticing that their pricing is noticably higher on my corporate travel site for the routes I fly.
Pretty easy decision to fly AA when their flights are cheaper and they are giving me Platinum EXP. I fly First allot more than I've done with UA in a long time, service is superior (CS, Gate & on the plane.)
So if you haven't gotten the message yet, I hope for your sake the price hike is the last clue you are going to need to hear before you switch. UA has proven they can continually make it worse for you, so I have no doubt they will. I'm through with this insanity. It's so much better, easier and cheaper to fly AA.
