Still not tempting me (although perhaps I should be). I effectively get 100% bonus on all flights (at least in 2000 I did with all the threshold bonuses) plus I got the 25% class of service bonus for all J flights (including certificate upgraded and paid J). I am still ahead with AC plus I get more lounge access etc. Now if Roots was part of oneworld or, heaven forbid, even SkyTeam I might be more interested . . .
