I agree that CX SL is better than others..

I will add that I was a Delta Skymiles SL for 2 years until Feb this year, before I got to SL in CX.

What do I get as an SL Skymiles member? Well, just a priority check in and boarding priviledges. No lounge access, no priority baggage and no free extra leg room seats..

Just an equivalent of MPC GR member...
