It should be noted that the agreement that NJS pilots are voting on as we speak includes a clause stating the agreement covers ALL variants of the A220.
With Airbus publicly stating they are developing an A220-500 which will be close to the size of an A320NEO, the implications of this clause could result in the original Bin Chickens slowly replacing Shorthaul pilots as the 737s are retired.
Apparently they have been offered a ‘vote yes or be redundant’ sort of “agreement”.
