In my opinion I don’t think BA needs to revolutionise it’s Mid-Haul Club World seat, just simply refresh it. Aer Lingus have done a very good job of their A321LR and BA could easily do this with 4 new A321neos. As they’re already densifying A320s it wouldn’t be too much work to add the Pinnacle seats to the old Mid-Haul A321s. It would be a win for customers in terms of product and BA in terms of fuel savings.
