I was scheduled to fly to Hawaii last March and the flights were cancelled due to COVID. My Expedia account shows two refund credits, one for me and one for my travel companion. Harry John Abreu $3547.51 Itinerary 744415****121 Marshelle Lynn Oxenford $3547.51 Itinerary 744415****121 We would like to reschedule this trip with Delta Airlines, however Expedia advised us that to redeem these credits we must contact Delta directly. How do we redeem these credits and apply them to another Delta Flight Any assistance you can offer will be greatly appreciated.
