I would like United to reinstate my expired Continental One Pass miles of 142,472. I was not aware of the details of the Continental Airline and United Airlines merger. I did not recall that I was notified the change from being a One Pass member to a MileagePlus member. As a result, the never expired miles in my One Pass program expired in the Mileage Plus account. Although I haven't flown since 2010, should I have known about the conversion, I would have participatied in other qualified activities in the MileagePlus program to keep my account active. I wrote 2 letters to United but they declined the reinstatement.
