I had already booked, but didn't realise the airline-style pricing (which I agree is great, and rewards regulars and early bookers) had ended. Are you sure, PN2, or was it just that the system had been tweaked slightly for this production? Sounds as though the cheaper tickets still exist but fewer of them and early in the run only.
Yes, it's true. Airline style pricing is no more. The box office staff confirmed it when I rang.
Saw this when it opened on Broadway. Not great but worth seeing again so I've booked.
