If you wait for it to expire & are willing to pat $75 they will turn it into a Luv credit with a 6 month window to use it and you can use it for anyone.
I had a big hassle with Southwest credits & I am pretty sure this is the case. I would definitely call their customer service & find out. It would be worth it. There is a special phone number you may need to call. I did, but I don't know what it was. It was not an 800 number, but the regular customer service people were able to direct me in the right direction.
Well, assuming you purchased a ticket that was non-refundable and that you were the one that actually paid for it.
Best of luck!
