Hi Everyone. Dont post much, but certainly read for helpful information. My TAP voucher expires on 4/1/2022 ( a covid issued one) and I called on Sunday morning at 7:30 (MST) and got right through. I had read best time to call is early a.m. (EST). Helpful gentlemen researched and told me they cant extend it yet until the day it expires or after and then they will extend it for 6 months. He also said if I used it prior to the expiration date for any reservation made from $/12022 to 4/1/2023, It would work. We are traveling end of April and it did work. Thanks everyone for all your help. I had emailed and tried calling them months ago to ask for an extension and finally had given up until I read these posts.
