And it's not just the material on the web site. I still have my 2010 welcome letter spelling out the perks:
Dear tom911,
There is no doubt that you are one of our very best customers, and we sincerely thank you for your loyalty to United. We will continue to make every effort to exceed your highest expectations every time you fly with us.
With your new Million Mile status comes some well-earned perks. You'll be receiving with our compliments:
Three (3) systemwide upgrades immediately
Two (2) confirmed regional upgrades at the end of every year
Lifetime Premier ExecutiveŽ status in our Mileage Plus program
It still surprises me that one poster here says those are worth about as much as a rock in a box and that UA can do anything they want to do with my lifetime benefits. It's just very difficult to buy into that policy after this letter promising exactly the opposite.
