Advice Please, Pretty Please

I'm desperate. And I'm reaching out to anyone who's passing through, bouncing by, or reads Ewan's blog everyday. Tell me what to expect with a 1 year old on a plane! We are less than 2 weeks away from our vacation, which includes a 6 hour plane flight there, and back of course. This will be Ewan's first flight. I've been frantically reading all the articles I can on Parents.com, but I need to hear real experiences. Any tips? Tricks? Things to ask? Bring? Am I being too paranoid? Or am I on the right track of being scared about a toddler who wants nothing to do with sitting still... especially for 6 hours! Shoot me some advice. I'm all ears. And it'll make me feel better. :)
