Sure, I'm just reacting because TOTP is like the textbook example of a system designed to work without interactive access to a networked resource. The whole as TM designed it has crappy affordances, but you could fix that without breaking the design.
Why though? Lord knows I hate Ticketmaster as much as everyone else but “airline model” sounds fucking terrible. I hope I never see the day where I’m removing belts and shoes to get into a concert.
To be fair though I always get at least somewhat reasonable concert prices by doing presale. Sign up for the artist’s “presale club” and/or get the credit cards that have presale as a perk. Get in queue ahead of time. You won’t have to deal with the dynamic pricing/public sale shenanigans that we hear about. On Reddit I often see people complaining about paying at least 2x what I paid for similar tickets.
