Delta has extended its rebooking window to up to two years
for customers with itineraries impacted by the Covid-19 virus.
Any Delta customer who is booked for travel through the end
of May can now rebook without a change fee for travel through May 2022. The
same extension applies to people already holding Delta credits for travel
itineraries than had been slated for March through May.
Delta tickets normally expire one year after purchase.
United and American tickets also must be rebooked for travel within a year of
purchase.
