Thanks everyone!
I agree that a *G would be the best way to go, however I dont have the time (probably not the funds either) to travel enough.
I'm a 19 year old student, and I'll be leaving in a couple of weeks to travel around the world for 2 1/2 months... I'll have about 8 star alliance flights, so I thought that it might be worth buying a pass to access the lounges.
I'm looking forward to doing some milage runs, etc. once I finish studying, as I've always had a passion for flying since I was young; especially class upgrades and the lounges
Cheers
Lucas
