I did baby tylonal before we got on the plane. You can also just bring some and give it to him if he starts screaming :). I never used a decongestant with my oldest and he took his first trip at 5.5 months (a 15 hr flight). His second trip was at 1 yr 3 months. I brought a portable dvd player with some movies. I'm not big on little guys in tv but you do what you gotta do in these situations. I also bought 2 smaller special toys he only got to see on the plane. New toys are so entertaining. Also brought snacks. Cheerios and such to pass time. Just plan a lot of 15 minute activities hehe. You'll make it! Don't worry! Worst case scenerio, you'll be walking around the plane a lot.
