T.,
I went through this exact situation last month!!! I flew from Salt Lake City to Baltimore, Maryland with my son, who was 11 months old at the time.
I bought a portable DVD player and brought his favorite Baby Einstein videos along for him to watch. This worked very well for a portion of the flight! You may be able to borrow a DVD player from a friend and then get a couple of DVD's from the library!
Also, I suggest putting a lot of thought into what you bring on the plane. I brought WAY too much stuff. I recommend trying to fit it all in one bag so you'll have an easier time getting to everything you need without feeling like a pack mule.
Remember that Security has very strict rules about what you can bring on the plane. Remember to dump out any juice or water you have before you try to go through Security. I had to leave my son's toothpaste and his sippy cup because it had apple juice in it. They will not make you dump out formula.
Also, don't hesitate to ask the flight attendants for what you need!!! You're probably paying a ton for your plane tickets and the least they can do is get you extra juice when you ask for it, or take a dirty diaper for you!!!
My last suggestion is (and this is a tricky one) to try to get as much rest before the flight as you can but without letting your little one sleep so that you'll be awake and ready to hold your baby in whatever position she falls asleep in (trust me, it probably won't be the most comfortable for you!) and also if you're rested, you'll be ready to entertain her with silly songs and talking.
Please let me know if you have any other questions that I might help with!
