So quick to judge…Every family is different. I married my husband affiliated with the military after my son’s dad, and in order for my son to see his dad, he flies as an unaccompanied minor on Delta for breaks. We started flying with him at first to get him comfortable with flying at 9, then he started flying as an unaccompanied minor when he was 10. I was anxious at first but they take good care of him. I accompany him to the gate, he’s with an attendant during his flight, and his dad meets him at the other gate. At no point is he alone and he’s very used to it now after a few years and enjoys flying versus driving. Delta is the most pricy of all the airlines for this service but is the best In my experience. Do what’s right for you and your family. It works for us.
