Booking Travel
Required traveler information.

To reduce wait times at the airport, we highly recommend that you enter your required valid passport information online at® prior to travel. You can do so during the booking process or post-booking at, during the online checkin process, or at the airport on your day of travel using a kiosk or at the Southwest Airlines Ticket Counter. You will be required to present your valid passport in addition to other required documentation at the airport on the day of travel.

Infants traveling as lap children.

Infants between 14 days and under two years of age can travel on international flights as either a lap child or in an FAA-approved car seat with the purchase of an infant fare. If you plan to travel with an infant as a lap child, you will be required to pay the taxes and fees that apply to the international portion of the infant’s itinerary. The taxes and fees must be paid prior to travel at the Southwest Airlines Ticket Counter or by calling 1-800-I-FLY-SWA (1-800-435-9792). All Southwest Airlines forms of payment are acceptable for lap children tickets with the exception of Southwest LUV Vouchers.

Unaccompanied minors under 18.

Minors under the age of 18 are not permitted to fly unaccompanied on international flights or any itinerary that includes an international flight. If a minor is traveling with an adult over the age of 18, they must be listed on the same flight itinerary.

Mixed passenger iteneraries.

For international itineraries, Senior Fares cannot be combined with other types of fares in the same reservation and must be booked in a separate itinerary. Upon completion of the Adult traveler’s booking, you will be redirected to complete your Senior traveler’s booking on a separate reservation.

Three forms of payment per purchase.

A maximum of three forms of payment per passenger may be used to purchase an international itinerary. One credit card or PayPal account may be used in conjunction with other accepted forms of payment including Southwest® gift cards, Southwest Airlines LUV vouchers, and/or reusable travel funds. All forms of payment may not be accepted at all locations. Cash may be accepted in some international locations at the Southwest Airlines Ticket Counter. PayPal is only accepted at

Taxes & fees for international flights.

Government-imposed taxes and fees on Southwest’s international flights (approximately $73 to $107) are typically much higher than the government-imposed taxes and fees on our domestic U.S. flights (approximately $11 to $25). Like all airlines, Southwest must include these taxes and fees as part of the overall fare quote at the time of purchase. But rest assured, we will do all we can to keep our portion of the air fare as low as possible.
