Even better would be an AF franchise HUY-CDG route!
Just remember who is now a majority shareholder of KLM - Air France.
1. There is no commercially vaible demand for a HUY - Paris route now or in the forseeable future.
2. If there was, it would be done by a AF/KLM partner, not Eastern.
As for the possibility of the EMB145 on the HUY - ABZ route, the SAAB is a much more efficient aircraft for that sort of service, as has been proved elsewhere, it can take a lot of pax and a lot of baggage whereas the EMB is significantly more restricted in that respect.
As things stand, HUY will probably be stuck with the JS41 but if the EMB does become a permanant feature on the ABZ route, fares will rise.
