Hey guys I'm trying to get a refund for a flight I booked for my girlfriend to go to Turks and Caicos. She lives in Vietnam and was denied her transit visa through the US which was a layover on the way to Turks and Caicos. As soon as the visa was denied I cancelled the flight and received it in future flight credits. The issue is those credits are useless as she lives in Vietnam. I'm trying to get a full refund, partial refund or even transfer those credits to my name. What are my options?
