Thanks United. I booked 6 months ago and now my seat assignments are toast. I have a trip to DC and then Latin America, and won't be sitting with my traveling compainon. Just because i thought i better check, when I logged in this afternoon - no assignments.

Guys I can't see how transfering a seat map from one system to another could lead to total chaos. Now i am facing a 10.5 hour flight in a middle seat. I know that at 360K lifetime miles and Premier Gold - I am not an uber important cusotmer. However, I bought my ticket, chose my seats, and now beacuse seat assignments were not transferred and, even worse, allowed to be reassgined - I am screwed. It is not proper, right or fair. Period

I played by the rules booked and did everything right. It wasn't an equipment change or weather issue. It was a poorly executed system conversion that penalizes the customer (full fare by the way).

Ideally, the original seat assignments would be returned and those that took the seats would be provided an eqivalent seat, the same generous offer being provided to the jilted customers.

If this is the New United - I wish you luck.
