For Sheba, I used to think the sweet spot was how they consider Europe to be a load of -stan countries that are typically expensive ex-EU. It's expensive to fly to KZ.
They consider "Europe":
Albania, , Armenia ,Austria ,Belarus ,Belgium ,Bosnia And Herzegovina , Bulgaria ,Croatia ,Czech Republic ,Denmark ,Estonia ,Finland ,Former Yugoslav, Republic Of Macedonia ,France ,Georgia ,Germany ,Greece ,Hungary ,Iceland ,Ireland, Italy ,Kazakhstan ,Latvia ,Lithuania ,Luxembourg ,Macedonia ,Malta ,Moldova ,Montenegro ,Netherlands ,Norway ,Poland ,Portugal ,Romania ,Russia ,Russian Federation ,Scotland [The independent country LOL], United Kingdom ,Serbia ,Slovak Republic ,Slovakia ,Slovenia ,Spain ,Sweden ,Switzerland ,Turkey ,Turkmenistan ,Ukraine ,United Kingdom, Uzbekistan
Like redeeming on LO to NQZ would be 30,000 in Y and 45,000 in C and minimal taxes from anywhere in Europe and its B787 operated.
Is there another?
