"Our guest was asked to wait with employees at the Service Center, as her connecting flight to Seattle was delayed for 1.3 hours due to a mechanical issue. While we had tabs on our young guest the entire time, we understand that she may have felt unsupervised in the crowded area and for that we are deeply sorry. We also think we could have done a better job communicating with her. Given her experience, we are carefully evaluating our chain of custody procedures for unaccompanied minors making connections through SFO and will strengthen processes to make sure our young guests feel safe and attended to at all times while they are in our care."
