BMI pilots will join at the bottom of the BA seniority list in the order of their BMI date of joining. BMI Captains and FOs will continue to be A320 Captains and FOs in BA....BUT....when a 'former' BMI Captain vacates his / her A320 command (in BA) then a former BMI FO will have first call on that command in BMI FO seniority order provided that the FO has remained on the A320 fleet, i.e. not changed fleets. It's the only way to ensure TUPE is preserved for BMI crews AND no BA pilot is disadvantaged which is what was assured prior to the recent vote.
