RE:RE:RE:Will Airbus Expand The A220 Family?.Removing 20 seats won’t bring the smaller a220 into Clause requirement as it will still be too heavy. Number of seats and MTOW needs to be within scope clause which is 76 seats and 86000 lbs. cs100 MTOW is 138999 lbs. removing 20 seats will not reduce weight by 53000 lbs.
