But now that it's called an Airbus, pilots no longer think it's an RJ

I forgot the CSeries was an RJ until it was taken over by Airbus! It looks like there was a JetBlue E190 that flew ANC-BUF.
From Wikipedia: "JetBlue set the record for the longest flight of the E-190 family when one of its aircraft made a non-stop flight from Anchorage, Alaska (Ted Stevens Anchorage International Airport) to Buffalo, New York (Buffalo Niagara International Airport), a total of 2,694 nmi (4,989 km). This was an empty aircraft on a non-revenue flight. The aircraft eventually returned to JFK after a two-month-long charter service with Vice Presidential candidate Sarah Palin."
