I agree but I don't have any specific information, my take on it is the Airbus will eventually take the place of MD in all aspects of operations. The MD are becoming more and more unreliable, increasingly costly to patch up/repair. With each canceled flight AAY is losing customers plus wasting flight crew allocation. And the MD adventures are starting to get the attention of the FAA, national media and watchdog groups. All of that is encouragement to park the MD and fly the AB, which are not new but a lot newer than the MD.

Looks to me like the plan is to switch over to Airbus aircraft as they become available for reasonable cost, similar to how management started with all the low cost used MD aircraft way back when. It's just a matter of time.
