Allegedly Blue Islands have listened to their passengers; they have said that they don't want to fly on Tris and therefore BI are selling them off and consequently the crews have been given notice.

A few months ago the ground crew were told they were to embark on a new adventure or some similar romantic imagery; aka given the boot.
It's all part of the MD's idiom.
