C.R.
I know how you feel. I always need to go to Europe to visit my family and I have a four year old son...
These are the things I did:
Go to the Library for some books are buy some
-Travels with Baby (The Ulitmate Guide for Planning Trips with Babies, Toddlers, and Preschool-Age Children by Shelly Rivoli
-Kid's Travel Fun Book by Loris and Marlin Bree
and there are lot more books at there on traveling with your kids
I also bought a cute card game (52 fun things to don the plane by Lynn Gordon)
And don't forget to take any activity bag with you. Put in: crayons, color book, reading books, DVD and movies, soft blanket, stuff toy, and whatever you can think of to keep your little sweetheart busy.....
I also back up a pharmacy kit: Ear Drops, Children's Tynelol, Children's calming drops that are hemopathic (you can find this at vitamin cottage), and whatever you think your little sweetheart might need on the trip. It's better to have it, then not to have it.
Also be sure that have your little sweetheart drinking or eating an apple or carrot or sucking on something when taking off or landing. This should prevent ease on the ear pain.
I also had a pair of extra clothes and his pjs. I tried to keep up with the routine. Like brushig teeth, putting on pjs (only if you can). Quiet time etc. (Also order a head of time the children meal for your little one)
Try to make it as fun as possible and start taking to your little one about the trip. This helps them prepare for it and they don't get scared of it.
I wish you a wonderful trip.
Hope this info helped.
Sending Happy Greetings from Mead
I wish you a fun trip......
