It's a short flight. What is it for you? 2, 2.5 hours? 20 minutes going up and 20 minutes going down takes a chunk off.
I have trouble reading on planes and am not sure why. I always put off reading the latest National Geographic until I'm on the plane. It's easy reading and has loads of pictures. It's my go-to for flying. I also watch TV sometimes. If you aren't sure if your plane will have screens, you can always bring something along. DVD players are cheap now.
Gum is fine. I don't know that it helps any, but I chew all the time, anyway, so always chew on the plane.
You can bring food and drink on the plane, you just can't take it through security. So if you wanted, you could buy something for the boys and feed them during the flight, which would take up time. They'll probably be so excited about looking out the window that it won't matter. Mountains look beautiful from the plane. Hope they get to see them!
Birds fly every day and aren't scared...and they have bird brains!! Be as smart as the birds and chill out.
I won't even wish you luck because you don't need it. It'll be fine.
Eta: Orlando's airport is exceptionally well marked. You would almost have to be brain-dead to get lost. Giant letters up on the wall. Giant numbers. They all glow. And when you get off, if you don't know where to collect baggage, just follow the crowd. They do.
