SkyWest’s plan to convert United Express CRJ200 aircraft into a new CRJ450 configuration is putting renewed attention on MHIRJ, the Mitsubishi Heavy Industries company that supports the global CRJ fleet.
SkyWest recently announced it expects to convert single-class CRJ200 aircraft operating for United Airlines into a 41-seat, dual-class CRJ450 configuration by 2028. The first redesigned CRJ450 should enter service in the fall of 2026.
The aircraft will include a United First cabin, a large luggage closet instead of overhead bins, larger main cabin overhead bins designed to fit rollaboard bags, and Starlink Wi-Fi service, SkyWest said.
The plan gives United and SkyWest a way to keep smaller regional jets relevant as airlines add premium seating and amenities to more parts of their networks. It also reinforces the importance of the companies that keep the CRJ fleet supported, repaired and available for revenue service.
MHIRJ was created after Mitsubishi Heavy Industries acquired the CRJ Series program from Bombardier. The deal closed June 1, 2020, and MHIRJ launched as the group responsible for service and support of the CRJ program. The company is headquartered in Montreal and provides support services for the regional aircraft industry, including the CRJ Series.
Today, MHIRJ provides operational, engineering and customer support, including maintenance, refurbishment, technical publications, marketing and sales activities for regional aircraft operators. The company also provides maintenance, repair, overhaul and line station services for CRJ aircraft in North America through facilities in Bridgeport, West Virginia, and Tucson, Arizona.
MHIRJ has also connected the CRJ450 to a broader push around fleet longevity and aftermarket support. The company says the CRJ450 opens “a new chapter” for regional fleets by combining regional jet efficiency with larger-aircraft amenities.
SkyWest listed 67 CRJ200s in service or under contract as of March 31, 2026, along with 46 CRJ550s, 78 CRJ700s and 38 CRJ900s.
