Air Wisconsin has reached an agreement in principal to operate 26 Bombardier CRJ200s for Delta Air Lines beginning in 2015.

The first 50-seat aircraft will likely enter service as Delta Connection in January 2015 with all 26 operating by the end of 2015, the Appleton, Wisconsin-based regional carrier confirms.

“Air Wisconsin is very pleased to have reached an agreement in principle to join the Delta Connection family,” it says.

The 26 aircraft are coming from Atlanta-based Delta’s wholly-owned subsidiary Endeavor Air, the mainline carrier confirms.

Endeavour is in the midst of transitioning to a fleet of all dual-class Bombardier CRJ900 regional jets. As part of this shift, another 12 CRJ200s will move to SkyWest Airlines in 2015, it confirms.

"Endeavor is looking forward to operating a single fleet of two-class CRJ900 aircraft," it says. "Eliminating 50-seat aircraft and going to a single fleet type is part of Endeavor’s plan to streamline operating processes and become a more efficient and viable airline for the long term."

The Minneapolis-based regional carrier operated 77 CRJ200s and 75 Bombardier CRJ900s at the end of September, a fleet plan shows.

Air Wisconsin operates 71 CRJ200s, the Ascend Fleets database shows. The aircraft operate contract with American Airlines-subsidiary US Airways.
