Great news for Boeing, now if EK can make good on the order for 100 747-8I's rumored last year, it would be a nice end to 2017.
Time goes fast, that deal was rumored in early 2015 as a pitch by GE Aviation together with Boeing straight to the Chairman of the airline sidelining Tim Clark. So basically this was about 3 years ago when this pitch happened.
Boeing's pitch of the 747-8I to TK could also have been around that time. It cannot have been to recent, and as we know TK didn't bite.
I can only see new freighter orders with the 777-9X coming closer and closer. We will see more of these smaller orders between some larger ones. Maybe Singapore Airlines or Air China will jump in at some point in the next couple of years, maybe ordering just enough for Boeing to raise the production a bit.
