Can M&M members expect another round of substantial changes with the introduction of the premium economy in 2014?

The exact details how premium economy will fit into the M&M program have not been evaluated so far and are not yet determined. Certainly the ticket value will be taken into consideration and differentiated like in the other class of travel. We are not currently planning to re-evaluate the existing booking classes: this was already done in the business class on September 1, 2012 and the economy class will be adjusted on January 1, 2014.
