Spirit Airlines charges an Unaccompanied Minor (UM) fee to ensure the safety and well-being of young travelers flying alone. This fee is typically applied to children aged 5 to 14 who are traveling without a parent or guardian. For Spirit, the UM service includes special attention from airline staff, pre-boarding, and supervision during the flight. The fee varies based on the destination and flight details but is generally a one-time charge for the round-trip journey. The service aims to provide a secure and comfortable travel experience for minors, with staff assisting them throughout their journey. Parents or guardians must complete the necessary paperwork and provide contact details for pickup upon arrival. This service ensures that unaccompanied minors are well cared for, making travel less stressful for both the child and their family.
