Rapid Rewards points are great - I've been converting Marriott Rewards points into RR points for years in order to get Companion Pass status (and I've been an A-List holder for years). However, starting on April 17th, the Rapid Rewards program will be undergoing a presumably massive devaluation... nobody knows the full details, since Southwest isn't publishing them, but RR points will no longer have a fixed value. I love SWA, and I fly them exclusively for business travel and personal travel when possible, but this devaluation is really stings. I had ~175,000 points in my RR account, but I cashed them all in for a few upcoming trips that we *might* take (there are six of us total, but one is on a companion pass).
So, if possible, try to book your travel before April 17 if using RR points -
