Thanks to these many replies on my post. It has been a great help to me so far. I would like to ask you guys a question (cause i'm not a FF):

Are you loyale to an airline/alliance because of the miles you get or because you really think that your prefered airline is superior (thus, the rewards are just a additional benefit). Or in a other way: Do FFP really create loyality or do they just create customer retention.

Cheers,
Flavio
