Agreed some of this is straying into non-red-eye territory. I think the generally accepted definition of a red-eye is one which departs late at night but is too short for a proper night of sleep (so basically 4-7 hours) so basically US domestic flights and JFK/BOS/IAD - DUB/LHR.
IMO, Asia - US and v.v. is way to long to be considered a red-eye no matter what class of service.
