- Log into your account and choose "buy miles" and then "buy status miles" in the menu on the left
- For me it took 80 seconds for the transaction to go through. The "you are now elite+" email arrived immediately.

And now I have to hurry to board my flight, get some sllep in TKs great seats after enjoying an excellent meal and then have my card printed tomorrow in IST
Bet regards,
