I would keep your husband's reservation for now. What if you don't earn the companion pass in time? Flight cost isn't going to go down, and if you cancel now and don't earn the pass in time, you'll have to rebook him at a higher rate. Also, what if the flight fills/sells out? SW flights are often full. For now, I'd keep the current flights. Once you earn the pass, cancel your husband's flights and add him as your companion. It doesn't matter if you booked "Wanna get away" and there are none left; as long as there are available seats on the flight, SW will book him. Regarding money already spent... you won't get the early bird cash back/transferred, but they might either credit previously-paid taxes to your credit card OR they will hold them as travel funds in your DH's name (which you can apply to the new, companion fare).
