France Air International uses Avro RJ 70. Why? Because we do it better
Have to disagree with you on that one. It's got out of date technology compared to modern ones.
In my opinion SSJ 100 is the best 70-100 seater A/C because:
1) Production slots - If you order an ERJ 190 for example you'll probably have to wait for a year or more where as SSJ will be delivered to you almost instantaneously to your doorstep.
2) Less FAs - I compared the ERJ 190 with SSJ 100-95 and although the Russian one is 10 seats shy of Brazilian one it needs less FAs so less money on staff needed.
3) Price - Although there isn't much difference now, just wait for a couple of years and see how the other RJ price goes ballistic and the SSJ stays more or less the same.
4) Good performance - Fuel burn age is relatively low, Range is quite long, Not much runway needed to land on, Quite high speed.
And the only real disadvantage SSJ has is slightly higher maintenance cost but that would be able to pay itself off when the ERJ price will go up. Plus It's Russian
