The regular CRJ already has a longer range than that - so are you mistaken, or is this just a bad joke?
EDIT: Ahh, I see it's not a joke, but that you've just left out a bunch of information. "The CRJ900 LR
jetliner provides an increased payload and range over the ER
version and can carry a full passenger load more than 1,030 miles (1,658 km) from a 5,800-foot (1,767 m) runway." Its standard range was already more than 1658 km, but doing it fully-loaded and taking off from a short runway is the key, I suppose.

Next flight.... who knows.
