B737Max9
Here we are, today Primera has lined out the plans for the next season.
3 b737 Max 9 will be based in BRU for the transatlantic flights. I guess few other bases will be soon announced for the b737 long range as they have ordered 20 machines.
I guess the range of the boeing is definitely the same as the 321Neo or even better as Bruxelles is even further than Paris or Stansted.
