It does look as if BA is trying to get more cabin crew out of BASSA as some will sign the new contract as it offers the guaranteed top up payment.
There will, though, be multiple agreements at LHR:
- WW on current contract
- EF on current contract
- WW on new contract
- EF on new contract
- Mixed fleet contract
This looks a bit messy as it will take several years for everyone to be on the mixed fleet contract.
