I had the value of an unused ticket of almost $900 that was set to expire in early May, 2020. I called at the beginning of this back in January or February when airlines started to amend their change and cancellation policies in response to travel disruptions caused by the pandemic. I had planned to use the voucer to travel in summer 2020 to go to China, SEAsia, or west africa). As time progressed travel to anywhere in the world became basically improbable, if not impossible and certainly not able to be done with reasonable risk to health. I was told the voucher would not come under the new cancel/change policies and to wait and see if the policies changed or travel became possible. I called every two weeks and received the same reponse regarding change/cancel but different information about when and how I had to use the voucher. What is in dispute was not the use by date, but when travel had to to started/completed. Different calls yielded different answers. I called yesterday and facing a 4.5 hour wait time I had could not wait. Called again 7 hours later - same 4.5 hour wait time. Tried chat online ... was told 5-10 min. for a response... 45 min. later someone responded saying - wait for it... call an agent. But.. it was a new number tha promised a hold time of 4-5 minutes. 35 minutes later I got an agent who understood my predicament. Was told that the travel had to commence by May 8th. Where could I go? She spoke to someone and told me they were going to refund the voucher. I think Delta recognized that there are going to be unique situations and that the generally they are encouraging people to travel in the future and to reduce risk of losing value of money spent. She said it wold be too complicated to extend the voucher and risky that something would go wrong so a refund was issued. Wondering what others are experiencing with expiring vouchers and how airlines are treating them.
