I once got 2500 miles for the "no middle seat guarantee" when I flew in an Q fare. But it was CO EWR agents who messed up my reservation, and bumped me from my exit row seat... I was so upset that I ended up in the last rows and in the middle for over 7 hours in an oversold EWR-LAX flight....
I got $150 voucher and 2500 miles... for the bump and the argument I had with the #@$% agent that did this....
The 2500 bonus miles are automaticaly added to your account if you are flying in a Y or equal fare... If the flight is in a different fare is opt to CO Care to granted it or not... but for elites Im sure they will do it...
