I have two complaints about United. First they devalued their frequent flier miles by doubling the miles required for travel unless you were fortunate enough to catch flight with the "economy" miles. Second, on a trip to Aspen, Colorado it was too stormy to land in Aspen so the plane was diverted to Denver. They used to offer bus service in such a situation to get people to Aspen. The last time I went they just told us that we could wait a day or two standby and hope for a seat or instead we could rent a car and get ourselves to Aspen. Absolutely no help. I would never fly United unless I absolutely had to.
