I was told yesterday that Diamond cardholders with a 25K + tier score will continue to get
free admittance to the AC Diamond Clubs in 2013.
In 2014, once the new tier levels are in force for the full calendar year 2013, you will have to be
a level 2 Diamond cardholder with a 40K+ tier score for free admittance.
Seems to make sense with the bonus tier point earnings now available.
