Which would you pick in Upper Class, if your goal were general comfort? I can fly JFK-LHR on a VS 787 daylight/daytime flight (leaving JFK in the morning and arriving London mid-evening), or I can take a redeye on a VS A350, departing JFK in the evening and reaching LHR early morning. I would intend to sleep on the redeye but read/work/watch IFE on the daylighter. Would love thoughts from any of you who have experienced both options.
