I hope I never have to fly this configuration. I've been in BA Clubworld - I actually liked that configuration. As a solo traveller, I wouldn't have been comfortable without the 'fan' that provides privacy between the seats. If I had been travelling with a companion, I still don't think I would have felt as comfortable with that arrangement as I would with a side-by-side configuration.
And...looks like with this config, there won't be any more chances to stretch out across the seats on less-than-full redeyes...
Also would have made it a lot less convenient for us to handle our little ones when we travelled with them...
