Southwest allows alcohol to be carried in checked luggage under the following conditions.
Southwest Airlines accepts small vaccinated domestic cats and dogs to travel with you in-cabin under the seat in front of you. All pets must be carried in an appropriate carrier, as indicated below. The pet carrier counts as either a carryon item or a personal item.
Pets will be accepted on a first-come, first-served basis until capacity is reached. Six (6) pets are allowed per flight with a limit of one pet carrier per paying Customer traveling on the same flight. However, from time to time, circumstances may allow for more (or fewer) than six (6) pet carriers per scheduled flight.
Pets must be checked in at the airport ticket counter, however Customers can still secure their boarding pass online, at curbside checkin, the airport kiosk, or the ticket counter.
We maintain the right to refuse acceptance of a cat or dog exhibiting aggressive behavior or any other characteristics that appear incompatible with air travel.

Please visit the TSA's web site for instructions and allowable medication in carryon baggage.
Southwest is not equipped to transport or provide medical oxygen or other hazardous materials and/or contained gas, either in the passenger cabin or as cargo or baggage. Any Customer who requires a constant supply of compressed or liquid medical oxygen cannot travel on Southwest Airlines. If there is a question as to a Customer's ability to travel the duration of a flight without the use of medical oxygen, we may request documentation from a licensed physician to verify that the Customer can complete the flight safely and without the use of medical oxygen.
Liquid oxygen cannot be carried onboard our aircraft. If a liquid oxygen unit is empty (and contains a gauge or color indicator verifying the unit is empty), then the unit can be transported, as long as the valve remains open.
