Wanderlust World Wanderlust World Baggage is inspected by the Transportation Security Administration before passengers enter the gate, but Southwest reserves the right to search bags again before passengers board their planes. All airlines are required by the Transportation Security Administration to allow one carry-on bag plus a small personal item on all flights. Cameras, laptops, purses and briefcases are considered personal items. The bags can't be larger than 10 x 16 x 24 inches.
Southwest Airlines only allows small cats and dogs that can be placed under the passenger's seat in a carrier for the duration of the flight. Small dogs and cats must have vaccinations and be transported in a carrier. Carriers count toward the carry-on limits. Flight reservations for cats and dogs must be booked through a Southwest reservation agent at 1-800-I-FLY-SWA (1-800-435-9792)
Children 11 and younger are charged child fares. They must be accompanied by an adult. Children up to 2 years old can sit on the parent's lap during the flight. No boarding pass is necessary. FAA-approved car seats can also be used. In those cases, a boarding pass is required along with a birth certificate. Passengers must provide a medical release form if the child is under 2 weeks old. Southwest Airlines reminds passengers that it and the Federal Aviation Administration strongly recommend that infants and small children who weigh under 40 pounds be secured in an appropriate child restraint device when traveling by air.
Anyone who takes up enough of the seat next to him to make the passenger in that seat uncomfortable is considered a "customer of size." These passengers are required to buy both seats. If the flight does not oversell, the customer may receive a refund for the seat after he has traveled. In some cases, the second seat can be discounted at the child fare.
Passengers who require special medical attention or have disabilities are encouraged to inform Southwest of their special needs before the flight.
