Flying on the 787-8(788) from MSY to LHR in a fewmonths with hubby. Cabin is mostly empty at this point and I am wondering what two seats will give us the best chance of some sleep. We usually each choose a separate window seat (don't need to be together) and would like to minimize noise and disruptions. We are each willing to climb over another passenger to get some rest. Seatguru reviewers seemed to suggest possibly 7A or 7K. Anyone with experience on this layout?
