Hi @rbay19,
Thanks for asking your question in the Southwest Airlines Community - welcome!
All of our planes are Boeing 737 aircraft, and the armrest is considered to be the definitive boundary between seats. The width between the armrests on our planes measures 17 inches.
We've got a great resource here for folks who want to learn about purchasing more than one seat for travel, so be sure to check it out. We can help you with the process, and make sure you get a refund for the extra seat when your travel is complete.
