Under qualiflyer as a TC you could 'borrow' miles up to 10.000 if you had not enough, for TCG that was about 20.000.

Is this still the case ?

What would happen if you would cancel your membership on dec 31 ? Would you have to pay those miles back ? At what price ? The price of a ticket ?

And on other question, what happens if you do not requalifly as a TCG ? Do you become silver for an extra year or is it totally going to be back in line again.
