A.T.
I would take the overnight & hold hiim during the flight, I'm sure he'll feel secure enough to sleep. You may not sleep well, but I bet he will. Good luck, I just did this a few days ago. He slept well, I didn't, but it's all about them anyway....goodluck....here's a tip someone just told me about equilizing hte ear pressure on the way up & down...a lolipop (natural one of course). Have fun.
