What is so confusing about non-refundable? It's not like somebody died and the heirs can't use the tickets. You pay less for WGA you can't get a cash refund. This policy is about 10x more customer friendly than any other airline where you basically lose 100% of the value of your ticket or you pay some absurd fee (multiply $150x# of family members). Any other airline and your money is already flushed.

OP should cancel her trip and use TTF to visit relatives, fly to Vegas for the weekend, or just visit some place that she's always wanted to go. The money is gone, might as well make the best of it. You'll be thousands of miles away soon so it will be a lot more time consuming and expensive to go anywhere in the USA. Look at this as an opportunity rather than crying over spilled milk.
