Yes, you can absolutely use your Southwest Rapid Rewards points to book a flight for your wife (or anyone else you choose). Southwest Airlines has one of the most flexible loyalty programs in the industry, and they do not require the "point holder" to be the person actually traveling on the ticket. To do this, simply log into your Rapid Rewards account on the Southwest website or app, select the "Points" toggle when searching for flights, and proceed with the booking. During the "Passenger Information" step, you will simply enter your wife’s name and her own Rapid Rewards number (if she has one) instead of your own. The points will be deducted from your balance, but the ticket will be issued in her name. A major benefit of booking with points on Southwest is that the "no-change-fee" and "no-cancel-fee" policies still apply; if you need to cancel her flight, the points will be returned directly to your account, and any taxes paid (usually $5.60 for a domestic one-way) will be held as a future flight credit for her or refunded to your original form of payment depending on the fare type.
