I have a little sympathy to United. Mistakes happen, and its their responsibility to accept them.
I wonder, if United will "prosecute" the members who filed a DOT complain on that. Can they cancel MileagePlus accounts of these individuals?
Not to be perjorative, but there's so much wrong with that question.
First of all, prosecuting someone for asserting their legal rights is a violation of just about every legal principle in common law. Secondly, what is the crime? Paying in DKK?
If UA want a REAL PR disaster on their hands they'll start closing MP accounts.
