Iberia adds nothing at all to BA's potential profitability, so why do it? It has the ability to take the Lufthansa path and add to its fundamental strength but by not growing its long haul fleet , other than via the conversion of a handful of 767s for the past ten years it has not made best use of its potential and slow portfolio. It needs now to get a grip of its own destiny. A merger with Iberia does nothing for it financially or strategically.
