BA212, Boston-London, leaves Boston at 6:05pm and gets to London 6h25m later, just past midnight in Boston but morning in London. I've had to get on such flight then get to London and endure an all day meeting. Even though I can stay awake and not yawn all day (valuable skill learned in college ), I've found I'm not at my peak performance. So I avoid this type of schedule the most I can.
UA930, San Francisco-London seems even worse. Leave San Francisco at 12:27pm, travel for 10 hours and a half getting to London about 11 pm San Francisco time.
My preference goes to 9 to 10pm departures, which allow for eating then normal time sleep. Out of SFO the latest transatlantic departure seems to be 7:30pm on BA - most flights are mid-afternoon.
Europe-Asia also has some lunch time departures. I find surprising that these flights are so popular with business travelers. Are most longhaul business travellers 24-h machines?
