For those who were wondering, it seems as if the overnight leg is about a 10-hour flight.
And here is a note from Chris with a tip if motion sickness is a problem for you (one day, we will be traveling on winding roads up (and down) Mt. Tabor. I had no problems at all, but if you are prone to it... here's one option)
At the travel meeting last week, I talked about Sea Bands ... they are helpful for preventing motion sickness, either on the sea or in cars on windy roads.
They are approx $8-10.. I got mine at Harris Teeter. I think Target carries them too, and Amazon. ... They are much better than taking dramamine. They have a little plastic button on the elastic bands that presses on an acupressure point in the wrist. They work for me... Chris http://www.sea-band.com/
