I'm on my 7th sun pass and I really haven't upgraded much since Feb 28 06 however booking in U class is important to me as availability of seats is pretty good. If this is moved to pure tango plus then I don't seeing buying anymore sun passes as booking last minute will not be as easy. Already since the 45 K SSWU change I have changed my routes to BA for overseas flights (after reaching 35K status miles). Once more AC giving elites no reason to continue buying AC product.
