Kids 17 years or less can travel alone as unaccompanied minors. Travelers should have every one of the expected records as identification, birth declaration and a govt. given the personal ID of the parents as well as contact details. Except for trips to and from Puerto Rico and the US Virgin Islands, minors are not permitted to book global trips. The charges will be $100 USD per traveler, regardless of airfare, as long as the movement is within the United States. If visitors aged 15 and up require assistance, the Spirit Unaccompanied Minor Fee will be applied.
