I just had to make the decision to use my Miles&More miles on an Y award ticket. I was looking into a flight to JFK from FRA on LH and after checking the prices for normal Y tickets I changed my mind and got instead of the one transatlantic ticket two inner European Y tickets to IST. I got much higher value. There are so many good deals on Y tickets to get over the atlantic that using miles for an Y seat is just a big waste. Don't know how it is with flights to Africa or Asia. Maybe its different there.
