One child over 14 days old and under two (2) years of age not occupying a seat may be carried free of charge when traveling with someone 12 years of age or older.
If you plan to travel with an infant as a Lap Child, you must 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 ticket counter or by phone.
All forms of payment are acceptable for Lap Child tickets except Southwest LUV Vouchers and cash. Pesos will still be accepted as a form of payment at the ticket counter in Cancun (CUN) and Los Cabos (SJD) only.
Employees may ask for age verification at any point, so please travel with a copy or original form of any government-issued ID, such as a birth certificate or passport for your child. A medical release for travel is required for any infant under 14 days old.
