There are a few people out there that think they will go to ABX but Im pretty optomistic it'll be DHK.
Perhaps the same people who were 100% certain the first 3 would also go to ABX? There are two chances of ABX getting the next 3: Fat and none. They'll go to DHK, nothing else makes sense.
Of course the best option would be to call Mr. Boeing and part exchange them and the 3 already in operation for some 777F's, but that's not going to happen either.
