I took my daughter on her first plane ride at 10 months. I didn't take a carseat though. If you have a carseat, they want you to buy a separate ticket for the kid, unless you're going to put it underneath. I held her on my lap the whole flight. Then when we got to our stop over, we rushed to where our next flight was taking off from, and when it was time to get on the plane, we did. Then, this flight was even longer. Our whole one way trip was 3 1/2 hours long. I brought some of her favorite toys, bottles, snacks, and her favorite blankie and baby. I also had a music player with headphones, and held it to her ear during the flight. Also, if you don't want her ears to pop when the plane takes off or lands(since this tends to make them fussy) you can try what I did. I made sure she was sucking on something, whether it's a bottle, cup, or pacifier, and I had 2 tiny paper cups with damp paper towels in them, and held them over her ears. It kept her ears from popping, and she was quiet the whole flight. She slept most of the time, even the flight back I did the same thing. Hope this helps, have a safe trip.
