Hey Ringa,
Dont try to analyse why they are asking for airbus to swap to boeing. If it means you will get a rest and a better lifestlye then take it.
There are delays in the arrival of the Boeings so it means I believe that 5 will come in November. They will need people to fly them.
Simple as that. Take the offer. By the sounds of the airbus guys as a whole, you could all do with a rest. Question is can it get any worse (probably !!!)
