Thanks the kindness reply from everyone!

However, my curiosity was increased which derived from the information of some responses. Hope someone can clear that for me.....

1. since most of people have more than one memberships, so... Does that mean the core services provided by airlines are less important that the membership status?
(i.e. core service and incentive benefit, which one is more important when choosing the airline?)

2. Is it true that different travel purpose would have different attitude toward the choice of airlines(FF programme)?

3. Do you think the INTERNET do any good for the FF membership development?

I knew that I've asked too many questions.
Maybe you are fed up with answering these questions. Anyway, I will cross my fingures, wish someone can help me out!
Thanks again for reading this and participation.
