I called Tech support and said "I am reading the FAQ and it says I have to register, but I can not find the link to register". They said:
** The period to earn hits will be Sept. 14th -Nov. 14th 2011
Registration will be at:
usairways.com/grandslam
They don't know when it will go live.
You will be able to call and register but they don't have that capacity on their end yet.
