Depends on how well you sleep on a plane and how your body reacts. MrsCP can fall asleep on an RJ before takeoff and I need to wake her to deplane, feeling great.

I can barely sleep on any plane at all.

Also consider the lag time between the flight and the climb. A couple of nights sleep does wonders, and I can do a lot of things for $1,000.

For some people, $1,000 is a pittance to feel better for a day. For others, it's a month's discretionary spending.
