I sent in three vouchers, sort of to test response time: One on 3/27, one on 3/28, and one on 3/29. The first one posted on 4/13, the next two on 4/18. Incidentally, I sent one to my daughter's account, hoping to restart her 3-year mileage expiration clock. It didn't work. Her clock still says 12/31/2001. Any thoughts on that? Does she need an actual flight?
