You would be much better off having either your husband or yourself apply for both of Southwest's Personal Visas (Plus and Premier), rather than both of you opening one.
You cannot transfer points from one account to the other without paying Southwest a transfer fee, but you can book flights for using your points for other people (e.g. your husband can use his points to book a flight for you).
Also, if you earn 110,000 Companion Pass Qualifying Points in a single calendar year (Jan-Dec), you will be awarded a Companion Pass with Southwest. This pass allows you to have a designated companion fly for free with you anytime you fly Southwest for the remainder of the current calendar year and the next full calendar year (even when your flight was paid with points). You can change your designated companion up to 3 times per calendar year.
Your points from your Southwest Visa are CPQP, so once you've completed the minimum spend on both cards, you'll have 104,000 points (50k bonus x 2+ 2k points for minimum spend x 2). You're only 6,000 CPQP away from CP, and there are many ways - some free - to easily earn the last 6,000 points.
Regarding points fares "disappearing": Southwest is rather unique in airline miles/points systems in that it allows you to book a seat on the flight with points as long as a seat is available. The amount of the flight in points, however, is directly tied to the dollar amount of the fare. So there may be 2 WGA fares remaining for your flight at X price - 2 of you could book your flights at that price (in points), and the other 2 would have to book at the next available fare. (Note that for this reason, it's in your best interest to search for your flights for 1 person and making sure it's the same price as what is shown for 4).
I've been checking out the united website and have a goal to fly to hawaii first class round trip for free! I wish I knew of this sooner! My husband and I are about to buy a house so after we do, game on !!!!!!!
