"due to economic circumstances, the cost savings of opeing a small Boston domicile, will allow the company to better position itself for future growth. A Boston base will allow more profitability, and enhance the marketability of Eagle for possible spin-off or sale. Therefore, a new simultaneous vacancy/displacement bid will be issued by XX date. All crew members are advised to ensure their preferences are properly noted and displayed in their 3*."

But, it won't happen until more of the senior BOS CA's retire/resign. Many have sufficient time in, and are commuting for the first time. A few have already gone, and the company will hold out until more drop.
