VCE and CDG can be operated by aircraft based in these locations freeing up NCL based aircraft to fly more routes or keeping encurrent setup but with more flying done from other bases. TFS should have increased frequency.
I don't think CDG was a matter of it not making money rather they thought they could make more money elsewhere.
CPH has been done. City places come and go. I just don't think CPH is on trend enough right now to sustain a 156Y service. In fact, easyJet just doesn't have a good track record when it comes to Scandinavia (except for CPH).
easyJet continues to deliver a strong performance at NCL. They're taking the fight to Ryanair. They chased Vueling out of town and are continuing to develop the base. Even the tiny increase of 6 seats on their A320 will help the economics of the base.
Haters gonna hate, but orange tails will be here at NCL in bigger numbers for years to come and staff will continue to be based here. There will never be a fourth aircraft.
