OP explicitly states he doesn't want to add the ticket to a google account. Fair to assume they wouldn't want apple either.

If it's a standard .pkpass, they could use it with an offline third-party app that can view those, e. g. PassAndroid [1]. Given Ticketmaster verifies Apple ID though, as mentioned in this thread, I'm not really sure it would work.
