As agreed between the union(s) and Air Berlin ExCom, 1/5 of the entire fleet expansions will occur in favour of LTU. Hence, no cheap and easy "outsourcing" to the disadvantage of the employees like it had/has happened before with DBA.
Yes, but they did not say if these 20% will be A320 or A330, which makes a big difference in the crew factor and the LTU pilots might end up doing short haul.
So I guess quite a few are willing to make a change and others may come back from EY, but as you say, time will tell.
