Wow do they have interesting quirks!
I bet much will change once they join *A.
Do you know how bad their fuel surcharge is?
Currently only 4,000 (!) miles are needed to reach "Blue" (*S?) and only 16,000 more miles within a year of reaching Blue to get top-tier Gold (*G?).
And they have cheap redemption options, international flights are just 11,000 miles in coach one-way.
Intercontinental LH flights in coach are just 30,000 miles one-way (50K in J, 75K in F)
