The difference between the 100 and 300 is simply a fuselage plug. That’s it.
Bombardier doesn’t need to make any exception during production or special changes in production line order.
In fact, if Delta decided they wanted to convert an in-service 100 into a 300, there’s an STC that allows Bombardier to split the fuselage, drop in the fuselage plug and voila... the 100 is now a 300. Way les$$ than buying a brand new aircraft and waiting for it to be built.
The unidentified European carrier that ordered 31 should have a better than expected delivery schedule as a result of Deltas delay.
Delta might be the first North American airline to operate into LCY. Unless Air Canada has similar ideas and gets a few aircraft early. Including some 100s if they’ve noticed it’s versatility?
It’s up to the route planners in the end.
