If C class miles are reduced from x2 to x1.5 then I shall be cancelling at least 2 C class long hauls with KLM and swopping them to Star. At the moment 3 x C asia or CPT C classes nearly gets me PE. Despite the drop to 70000 I will need nearly 4 C class returns. It will just become too difficult to stay PE under this system and will make the promised lifetime PE too difficult for me to achieve.
