I have a large credit thats an canceled international ticket that will be expiring by the 26 Sept. [I can change the flight to any time within 330 days of 26 Sept] Since I'm not sure about how I will use the rest of the credit, are there any flights that I can book to break the ticket into the flight+the electronic travel credit? I'm aware that I'm going to have to pay the ~$300 fee to break up the ticket (2014 rules on canceled travel) Are there any airports that I should be looking at that would be the cheapest? (If it's MKE I can do a one way due to the train) I'm based out of ORD. Another question is: Do I actually have to take the flight? What happens if I don't? Would I end up loosing the remaining ETC?
