Thanks for spotting that! Our database groups Challenger 850 under CRJ so that's why this order from Jetair Flug has been pulled from the database for January.
The Fleet Watch analysis is done on aircraft type basis and not on the user-end application. For example, Boeing 737 figures might include BBJs. The Bombardier CRJ type is classified as a regional jet and includes Challenger 850, 870 and 890.
