We booked airfare to Houston for a family cruise vacation on Southwest Airlines. Due to Covid we had to cancel the airfare twice because the cruise line (Carnival) is under a non sale order. For the second airfare booking we used the travel funds from the first reservation leaving a small travel funds balance that expires on 9/7/2022. When Carnival cancelled again we cancelled the airfare and received travel funds that expire on 8/15/2021 which is one year earlier than the original Southwest booking experation date. In other words, Southwest is saying, if we didn't use part of the original travel funds all of the funds would have rolled over with an experation date of 9/7/2022. To me this is totally unfair. To me this was just a continuation of the original Southwest booking and we should be granted the better travel funds experation date. We have since rebooked the same cruise for a Jan 2022 sailing date and want to use the travel funds for the airfare. I have called and emailed Southwest requesting them to extend both unused travel funds from our two reservations to the same experation date 9/2022. Thus far Southwest won't change their position on the expiration date for the second reservation. This is a Covid mess that was beyond our control. I feel Southwest is being unreasonable by not granting my request.
