Such a strange offer.
$9500 for 18,000 Miles
$10,000 for 27,000 Miles
$13,000 for 44,000 Miles
I'm already at $16,500 in spend so the goals would put me at $25K! Ouch.
Also as a 1K, I'd get 100,000+ miles for the $9500 bonus. ???
And lastly, I routinely get accelerator offers that could get me 18,000 miles for pennies. I have offers of $243 for 9000 miles on the next 5 flights I have booked, so for $1,250 I could get 45,000 bonus miles.
Computer algorithm gone awry?
If the first tier had "and Global Services" for 2018 I *might* try for it, but otherwise, have no idea what they are thinking!
