Ok, to Israel its for sure worth it most.
Now the question is, how one can credit miles there without flying. SPG is not an option, does Amex? Most guys here (I would not dare to include superflyer or steve2 ;-) ) dont fly that much to collect enough way the old fashioned way!
By the way, some rules are quite bad
