Etihad offer a number of ways to purchase and/or boost Guest miles. I assume that Tier miles can only be acquired through flight activity but I want to be sure.
I'm only 1200 tier miles short from the next tier and I have a long international leg coming up. It would be nice to get to the next tier before I take that flight.
Can anyone confirm - any way to purchase, boost, accelerate, whatever Tier Miles?
