I'm curious what people think of the feasibility of this. I have an economy ticket on United from LHR to IAD and back that I am not going to use. I know that the ticket is non-refundable. However, the rules for the ticket indicate that if the ticket is upgraded to a business class ticket, it could be canceled after paying the normal economy "cancelation fee." A separate section of the rules indicates that the cancellation fee is 50 British Pounds (about $75). However, there is a syntactical ambiguity in the sense that it is not clear whether the cacelation fee includes the initial cost of the economy ticket in addition to the 50 pund fee.
What I would like to do is get the ticket upgraded to Business Class and then cancel the reservation, paying only the 50 pound cancellation fee.
What do you think?
As a related question, can I use a purchased international economy ticket on a domestic route? I know I would have to pay a changing fee, but is it possible?
