Not sure you're right there 'haven't a clue'
To my knowledge BMI intend to run BMed as a separate and independant carrier for the time being. With no changes to anyone's terms and conditions a sale like this can be completed with little or no delay, in essence nothing has changed.
BAConnect's business model is wrong. Period. Flybe clearly do not want to absorb and airline with the losses that BACon is racking up and so changes to employee terms and conditions are required in order to make the combined airline a goer. Understandably, Flybe do not wish to harm their own business in the long term.
