The Royal Opera House have clarified their pricing policy for the 2012/13 Season.
For some main house productions - like The Minotaur - the prices will be the same as they were at their previous showing. For others - only Tosca and La bohème are mentioned - prices will be lower than they were before. (The price drop will apply to all tickets, top to bottom.) And for high-demand productions such as The Ring, Don Carlo, La Rondine and Nabucco, prices will be higher.
Here are the prices for the first part of the season (image copyright Royal Opera House):
