Just a word of advice to anyone hoping to get more status by year end and are flying close to Dec.31. If the miles post in January you will be able to make a case for having them accrue to your 2012 miles. AC has been quite ready to adjust in the past;it usually takes a simple phone call to AE. If you absolutely want the miles to post in 2013 it may make sense to withhold your AE number and then report the fight as missing points in January. Of course for any threshold levels reached by year end ecerts will be good until Feb. 2014. As AC has given us advance notice about what our choices maybe for the new altitude program one should think about what options they will take for their tier level when the claendar turns to 2013.
