OS is planned to be a small niche carrier in a very small market.
BA are risking potentially huge losses, during the utterly inevitable strike action, over this '
niche' operation. Why do you think that could be???
Have you read the baplane-bapilot campaign website? If you familiarise yourself with the likes of 'Jetstar; and 'American Eagle', you will begin to understand why we will not allow this 'mainline' operation to exist without 'mainline' seniority for it's pilots.
it would block experienced F/O`s to move upward to command.
How can this be, if as you say, no mainline pilots will bid for OS T&Cs? (BALPA have already stated these will not change) In any case, what will prevent OS simply recruiting Direct Entry Captains from the open market ahead of all their FOs? And why wouldn't they? There are apparently plenty available. Not least, retired BA captains!
Your command upgrades are to be done on merit, and you have no representation at the table!
A common seniority list simply would not fit.
Why?
I think you may have been fed a little too much propaganda!
Try reading a little more of the baplane-bapilot website.
Bon chance.
