Seat62K,
No upgrade - that's the whole package. Amassing miles is fine, but you need to use them at some stage, and my health isn't such that I can say that I'll be able to use those miles in 4 or 5 years. The chances of going to Oz and Kiwi again is very remote, and we do get back on the 25th wedding anniversary. Plus I've amassed over 50,000 miles so far this year.........
The difference between Club and First is certainly not as great as the difference between WT+ and Club.
