He does not have a degree that is, in any way, relevant the advice and statements he makes. He has as much experience running an an airline as a gate agent.
It has nothing to do with age. And I did not crap on McDonald's workers. Don't put words in my mouth.
Again I don't see how one needs to have an MBA (you didn't say MBA I know) to make a video about an airline. He actually does have relevant education but as an aviation youtuber I don't think he'd talk much about it no?
