Did you call and have the pet added to your reservation? If so, you' should be all set (even without receiving the confirmation email). You'll still have to check in (online) and then again at the counter, where you'll pay the $95 fee. Southwest allows up to 6 pet carriers per flight, so it's unlikely you'd be turned away. Right now phone reps are overwhelmed (and understaffed). There's a significant weather event happening leading to many cancellations, and they're experiencing IT issues with the website (again). The missing confirmation email is probably just another IT glitch. But if you'd feel better double-checking that the pet has been noted on your reservation, wait a few days (if possible) and the hold times should be shorter. Good luck!
Southwest Airlines is the only airline we fly because they allow me on board in my carrier under the seat and they have always been extremely pet friendly and accommodating. We’ve had zero problems boarding with my carriers in over 2 years of frequent flying with me in tow. I am 15″ from floor to top of shoulders, 16″ from base of neck to base of tail, 19inch chest girth and 19 pounds.

Unlike some airlines, Southwest does not allow pets as checked luggage. If you wish to travel on Southwest with a pet, you must take it in the airplane's cabin with you. Southwest requires that you house your pet in a pet carrier large enough to completely enclose the animal. Pet owners must pay a fee of $75 each way, as of publication, to travel with an animal. If you don't have a pet carrier, the airline sells approved carriers for $45. Pets must be vaccinated, although Southwest doesn't require the owner to show proof of vaccination.The airline requires you to place the animal carrier under the seat in front of you for the duration of the flight. Seat dimensions are available on the airline's website. Passengers are allowed only one carrier, although you can transport two animals of the same species in a carrier, space permitting. Southwest considers a pet carrier as a carry-on item or personal item, which means it must adhere to carry-on item size guidelines. You can travel with a pet carrier and a purse or briefcase, but not a pet carrier, small suitcase and purse.Though I was a tad worried at first that Southwest does specify that, “the cat or dog must be completely inside the pet carrier and be able to stand up and move around the carrier with ease.” Benji kinda plays with that limit, but they never checked or questioned me about it on the multiple trips I’ve taken. Pets traveling in cabin/carry-on must be transported in soft-sided or hard-sided pet travel carriers that are leak proof and ventilated on at least two sides. The carrier must be large enough for your pet to stand up, turn around and lie down comfortably. The pet carrier must fit under the seat in front of you. The under-seat dimensions are as follows: window seat - 19" L x 14" W x 8.25" H; middle seat - 19" L x 19" W x 8.25" H; aisle seat - 19" L x 14" W x 8.25" H. Southwest Airlines allows only one pet carrier per ticketed Passenger. The carrier may contain two (2) cats or dogs and must be of the same species per carrier. Pets must be secured in the pet carrier at all times while in the gate area, during boarding/deplaning, and they must remain in the carrier for the entire duration of the flight. Failure to follow this requirement may result in denial of transportation of the pet onboard Southwest Airlines.
