Thanks Ottergirl for your answers.
Just to carry on the debate though, just say the new Boeing/Airbus superjet turns up, you would imagine New Fleet will crew it. It is the only way BA could capitalise on new contracts within say 10-15 years. As the new superjets turn up, the old smokers will go out to grass along with the crew on them, unless you sign to New Fleet and a reduction in T&C's.
Pure speculation, but I am just trying how BA get to save this money.
