Obviously your employer has an interest in this EBA being agreed to.
From what i have read the FAAA would also like you to agree to the EBA.
Has the FAAA sent you anything with the pro's and con's of this EBA especially compared to your existing EBA?
If they have not ,then I would suggest a face to face meetings with the FAAA so that they can answer questions directly .This also gives the union an idea of where the crew stand on it.
This way if the majority of crew are not happy with it you can relay that feeling directly to the union or vice versa.
