The new owners of Eastern Airlines have canceled an order for 20 Mitsubishi MRJ90s and waived purchase rights on another 20, the manufacturer confirmed Friday. The cancellation follows Eastern’s sale to Phoenix-based charter operator Swift Air over the summer. Mitsubishi attributed the decision to a change in Eastern’s “business configuration” and not to delays in the MRJ program’s development. With last summer’s merger Swift Air’s fleet numbered 16 Boeing 737s, including three Eastern Airlines-branded 737-800s.

“The cancellation has been made after extensive discussion between Mitsubishi Aircraft and Eastern (EAL); we determined that cancellation was the best option for both parties,” said Mitsubishi in a written statement. “This is a matter having to do with the changes in EAL’s business configuration. After [its] sell-off to Swift Air, EAL returned [its] license (AOC) to FAA and has withdrawn from [the] aviation business.”   

The MRJ’s firm order count now stands at 213. The program has also collected options for 170 airplanes and purchase rights for four.
