Questions have been raised around whether the Sukhoi SSJ 100 was a good fit compared to the current wonder aircraft, the Airbus A220.
Passengers
The A220-100 was always going to carry more passengers than the SJ 100 as it is simply bigger and longer. The maximum capacity of the SJ 100 is the normal seating capacity of the A220-100. But both aircraft seat their passengers in a 3-2 configuration in economy.
Range
Airlines will be attracted to the range of this aircraft as it would be more flexible for longer routes. The SJ 100 is a smaller aircraft only just but falls short in nearly every way when compared to the Airbus A220.
SJ 100 list price: $50 million USD
A220-100 list price: $81 million USD
