Recently had a return trip from LHR to ORD on the High J Polaris 767-300. I was travelling with my wife and on the outward bound flight we had 1L and 2L, the latter being slanted towards the aisle, but still with a good window view. On the return however we were further back in 3L and 4L and whilst my wife had 3 windows nicely aligned to her 3L seat, this was the full extend of the view from 4L. Not a major problem as it was a night flight for most of the journey, but worth taking into consideration should you wish to have a good window view.
So whilst I could just about see out whilst on finals to LHR over central London, my wife could take a lovely photo of the sun rising!
