I noticed with some dismay that Amrak decided to let unused coupons expire in late 2020 rather than extending again. Given the covid numbers in my area, it would have been irresponsible to travel by train for anything less than critical purposes. I get that they were under no obligation to extend further, but still disappointing. Contrast that with the airlines, who have generally been very generous with extending the expiration dates of credits, points, status, etc.
