Lukas, with the F100 (and Embraer 190/195) this strongly marketed at the moment it seems a bit difficult for Boeing to attract new customers for the B717, as they squeez the B712 froom the lower end, whilest Boeing and Airbus are actively working on the upper end with the B73G and A319.
Again, we come to the missing family concept which is probably the main point why this bird isn't selling. Should Rekkof really decide to re-engine the F100 with the BR715 its the end of the B717.
Taking this into account I can only see existing customers converting options on the 717, which reduces it basically to AirTran and maybe Spanair/AeBal. QF
can be ruled out, these frames will be on the second-hand market before long, OA
is a no-brainer because of zero money. For TZ
12 frames is simply too small an order (besides, Pembroke still has around 12 frames in the book which are not yet leased, wonder if Boeing would count a lease placement of 12 frames as new order in this case). Hawaiian doesn't need more. Turkmenistan max 1-2 additional frames.
For basically all other carriers the Embraers and Fokkers offer more at the moment. Besides, now that Airbus and PW
have started a major campaign for the PW
-powered A318 it will get even harder for Boeing to get sales.
