The OP was aiming for LTP with just under ~4k SCs to go. So probably 3+ years for those extra 400-500 if they maintain WP throughout. Many more years if less SCs per year.
Hopefully some more interesting SCs earning opportunities will open up over that period.
I went for PCs for the ability earn SCs on awards flights since I’m sitting on a very large points balance. I’m already LTG but the possibility to maintain WP without forking out thousands of $ is very attractive. My wine cellar is also well stocked...
