i just realized this was a very old post that was bounced....don't know why...
but since i already mistakenly posted i'll leave these few items in....sorry i didn't notice the bounce before i posted..
prescription medicines (in your carry on bag)...
travel snacks in the carry on bag for the kids...
something to keep the kids busy on the plane (depending on ages - puzzle books, pealable nail polish for little girls, playing cards, coloring books and crayons, etc.)
