I can now report that all SWA travel funds for all of my family members have been updated/extended in SWA's system and all expire on 9/7/2022. DD and I each have close to $1k in travel funds, but hopefully we'll be able to use them over the next 2.5 years. I will certainly use mine. DD will be a little tougher since she will be at university in Scotland, but with that amount of time, hopefully we can use a good chunk for positioning flights on summer trips in 2021 and 2022 when she will be joining us since we often need to do short positioning flights to a gateway city. Really happy I don't have to call SWA about my funds that expired on 4/1 that were missing a couple of days ago. They are now there with the new expiration date.
ETA: Still waiting for the new expiration date on DH's CP....
