You can go to the traveling with pets link under customer service on Southwest.com I put the link below: https://www.southwest.com/html/customer-service/traveling-with-animals/pets/index-pol.html?clk=GFOOTER-CUSTOMER-PET It doesn't mention anything about your pet being allowed in its own seat. Only in a carrier that fits under the seat in front of you. I would recommend you call Southwest Customer Service and speak with someone directly. The animals you saw on the previous Southwest Flights could have been service animals. Good luck!
