That’s not the story I’ve heard. What I’ve read are stories of airlines who regretted the deals and went after those who used them extensively, looking for excuses to revoke them:

Anyhow, the Mark Cuban article says almost nothing about how the airline treated him, it’s just a light human interest story about an unusual and quirky thing a famous person did.

If the claims in the article are true around 2.5k cancellations and ticket reselling, I'd say they found great reasons to revoke these airpasses.
