Take some pee pads in the carrier with you so you can put them on the floor of the bathroom during the flight if necessary.

There is a new motion sickness medicine called Cerenia that doesn't drug them at all but keeps their tummys settled. I've used it in the car and you couldn't even tell that he was medicated except he didn't throw up. Some people also recommend ginger snap cookies as the ginger is good on their tummy. Trouble is, you need to give either one of those before he gets sick, otherwise might not be able to keep it down. I highly recommend the Cerenia.

Be sure to take a little cup or something for him to drink out of. You want him to eat a little on the flight, and he may not want his regular food. Buy a chicken/turkey sandwich after you go through security, and he might be more likely to eat a little of the chicken. Otherwise, buy a jar of baby food, chicken meat only, and use that. Those jars are small and could be put in your quart-sized bag with your liquid things you are bringing on the plane (you can take any liquid under 4 oz. as long as they all fit in a quart sized zip lock bag. Call your airline if you have any questions about this).

Take a warm blanket for him. It gets very cold on the long flights and the floor can be quite drafty.

Best of luck.
