I avoid red eyes like the plague but scheduling forces me to do one soon. I need to attend late afternoon functions in Boston the day of arrival. My options are:

-- Non-stop in UA domestic first to Boston, check in to hotel on arrival guaranteed, sleep for 3 hours or so and get out of the hotel around lunch time.

-- Flat bed flight to JFK, stop in the new Delta JFK lounge for a shower and breakfast before heading on to Boston on Delta in first, arriving a little after noon. (I'll be using my Platinum Amex to get into the lounge, and it appears I would have access to all the facilities there.)

I'm leaning toward the flat bed with connection because otherwise I won't get much real sleep en route at all, but even if all goes well I won't be able to sleep more than 4 1/2 hours or so on the plane.

Any advice?
