Not sure what the argument is here. A220 is a smaller narrow body jet airliner. Whatever hours you have will be better than having nothing and if you can't transfer your skills from an A220, to an Ejet or over to the A320 or 737 you probably should go clean toilets instead. Pretty sure the US airlines will not care at all if you have 1500+ hours on an A220 or 737. Considering the amount they are paying, shelling put for a type rating will be cheap for them. I've seen SAAB pilots leave and fly 747s over there, so does that mean the SAAB rating is better than having an A220 in the log book?
