There is much misunderstanding here. Nobody is saying that the jobs are to be protected for BA mainline pilots, nobody is saying that external recruitment cannot happen.
What we are saying is that any pilot recruited from outside BA for OpenLies must be on the BA seniority list i.e. a new recruit from outdside BA will be placed on the BA master seniority list. Some junior BA FOs may well apply for OpenLies but their seat in mainline will have to be filled from somewhere so the jobs in OpenLies will be filled by recruitment either directly into OpenLies or directly into mainline to replace those moving across to OpenLies.
To those saying OpenLies will not affect BA mainline look to the QANTAS/Jetstar sitruation and then come back to this thread.
GO was a completely different kettle of fish as was Cityflyer.
