Thanks for the replies.
Apparently bereavement fares are for immediate family members funerals only, and that is not the case for us.
I am wary of Hotwire as you cannot choose the time or how many legs of a flight you might get. My daughter made this mistake once and ended up with such a crazy itinerary, 4 flight legs taking her way out of her way, and leaving a little before midnight. They also will not allow you to book same day RT flights.
Southwest is the same price as Alaska and would take me through Salt Lake or L.A. taking almost as much time as driving.
I do an have Alaska companion fare, but plan to use it for Hawaii next winter.
I think I am going to fly my husband alone, using miles one way and paying cash the other, flying RT the same day. Costco is showing a car rental for $16.00.
