Hey! I was looking on google for an answer to something else and saw your question. I literally just made an account to answer lol. I’m flying with my ESA for the first time in a few days and I had no idea what to do. Call Southwest, and make your reservation over the phone. That’s literally the only way to do it. I’m flying with my 95lb dog, and to get an extra seat for him they added an extra seat onto my reservation (which you can only do over the phone). I had to pay double for another seat, BUT if you call them back after your flight, they’ll reimburse you for your ESA’s ticket since technically they fly free. Hope that helps!
