The minimum age for children to travel alone as adults paying adult fares varies: Kids have to be 12 years old to fly alone on domestic flights with Hawaiian, Southwest, Air Canada, and WestJet; 13 years old on Alaska; 14 years old to fly as an adult on JetBlue; and 15 years old on Allegiant, American, Delta, Frontier, ...

Yes, a 14-year-old can fly alone, but the rules vary depending on the airline and whether the flight is domestic or international. On most major U.S. carriers, children aged 12 to 14 are generally allowed to fly as "young travelers" without the mandatory Unaccompanied Minor (UM) service, though parents can often opt-in for an extra fee (usually $150 each way). However, some international airlines, such as British Airways or Virgin Atlantic, have a minimum age of 14 for solo travel, while budget carriers like Ryanair or EasyJet require passengers to be at least 16. If your daughter is 14, she will need a valid government-issued photo ID (or a passport for international trips). Even if the UM service isn't required, it is wise to provide her with a notarized letter of consent from both parents, a list of emergency contacts, and a clear plan for who will be meeting her at the gate upon arrival.
