I like a lot of the thoughts... but nobody has mentioned PJs and a mattress pad or something like that on the ULH flights. I did the ATL-BOM on more than one occasion and while the flat seat is really comfy for a good slumber, being able to change into something other than my jeans/slacks and sleep on a softer surface than "leather" would be a great way to make the seat even better. This doesn't have to be for the average intercontinental flight, but perhaps for flights over 10 hours or something.

Oh... and they ARE revamping BE, it's not a rumor or a pipe dream. It's a fact.
