Yes, you can fly British Airways (BA) if you are under 16, but the airline has strict rules regarding unaccompanied minors. In 2026, British Airways allows children aged 14 and 15 to travel alone on both domestic and international flights, provided they have a signed "Young Flyers Travelling Alone" consent form from a parent or legal guardian. However, BA does not offer an escort service for these teenagers; they must be capable of navigating the airport, security, and boarding processes entirely on their own. For children under the age of 14, BA policy states they cannot travel alone under any circumstances; they must be accompanied by someone aged 16 or over on the same booking. If you are looking for a service where airline staff look after a younger child throughout the journey (the traditional "Unaccompanied Minor" service), you would need to book with a different carrier, as BA discontinued that specific service several years ago.
