Red eye: flat bed with connection or non-stop?
Can you sleep in the first class UA seat?
When I take red eyes, even the brutal ones from the west coast to DFW or ORD, I can sleep just fine in the first seats. If you're like me, I'd opt for the nonstop with the guaranteed hotel room and a real bed at the end. Even delta flat bed is still on a plane and 4.5 hours isn't enough sleep no matter how comfy the bed is.
