Welcome to FT.
I too am sorry about what happened. If you had been around FT at the time you took the challenge, you would have seen that the challenge required a certain fare/booking class. One thing I have learned is that a mile is not a mile - when you book in the higher fare classes, you get bonus EQM's. That is why I went to Bucharest twice in the past 4 months in B class and why I am going to London next month with CO in Y class. They all add to my EQM balance, at a much lower cost than normal domestic tickets in the cheapest booking classes.
