Thanks everyone who has contributed to this topic! I wish TYN didn't change their rules as I'm back at around 90K TYP
I just called Delta today to cancel my trip. They charged me $150 as expected and told me I have until 1 year after my original ticket purchase date (2/17) to book another flight.
If I book a cheap flight, will the rest of the money expire in a year after re-booking? I can't really plan any travel at the moment - is there a better way to deal with it then wasting the money on the cheapest Delta ticket I can find?
