If he wanted to use his celebrity leverage for the benefit of the pilot group in this negotiation, he could simply set all of these videos to private until the negotiations are over.

The videos say "In Partnership with Envoy" and the Envoy logo is shown or Envoy mentioned numerous times adding that marketing benefit. His audience seems to be mostly high school kids and college kids in flight schools, (aka future cadets with shiny jet syndrome).

His videos are factual in what he describes, but he conveniently avoids or sugarcoats the negatives. For example, he describes his lines as same day commutable, but didn't mention that he needed to be at the Fargo airport before 5am to commute to a 5 leg day that ended 18 hours later. Or that his commutable on the back end trips only have 1 flight that leaves within an hour of his block in (hope he doesn't get delayed). These are things that someone who spent time in the industry will notice with caution, but they sound great to a starry-eyed CFI with a cadet application next to the computer.

He is specifically describing line holding in terms specific to Envoy. It doesn't seem like he knows or has researched line holding at other airlines. He just mentions "it varies". Yeah, it varies... in ways that are better at many other airlines.

I will give credit to the CAs in his videos. It seems like they are reluctantly agreeing to be in his videos as you usually only see the back of their heads.

I'm not sure if Envoy is paying him extra on the side. This kind of product placement would be worth big money to other youtube influencers. I haven't noticed any other revenue streams on his Envoy videos. His 2+ million views on Envoy would probably have earned him about $5,000 - $10,000 if he just had YT ads running.
