I couldn't travel internationally last summer to see family due to Covid. Iberia gave me a voucher that expires June 30, 2021. I used part of it to reserve travel in early June so I don't lose my money. I don't want to travel to Spain this year as it isn't safe. US has Spain on their Do Not Travel list. Iberia won't give me a voucher to extend it. I've tried dozens of times to get a voucher for travel when restrictions are lifted yet they are not agreeable.
