They already have at least 2 Airbii with their name plastered on the side... Not to mention that about 0.000001% of their clientele will even notice, never mind care.
I don't think that strapline would preclude them operating their own A330's. Having said that, they might get tempted into a deal on some 767's, should they re-enter production. Are the terrible teen dreamliners still kicking about or have they been bought?
