Alitalia actually operated Embraer 145 (48 seats) and ATR-72 (66 seats). Then they have A320/200 (131 C/Y) or Mdd-82 (133 C/Y). So they have a big gap from 66 seats to 131. Also they have 12 A319 on order.
They told they want a 80/90 seats plane.
So which plane do you think they will buy??
The possible options are:
A318 (it's A320 family, so they can have some economy)
B717 (Some part of this plane are building from Italian Alenia factory and they can use on the some Mdd-80 pilots)
EMB-170//190/200 (from 70 to 100 pax)
EMB-190/100 (90 pax)
Avro ARJX-85 (probably the cheapest for 85 pax and can be used in some difficult airports like Florence and London City)
I think they will buy EMB-190/100.
What do you think??
