How to Fly With Your Pet?

I've driven across the country with her a couple of times, and she's lovely in the car, but i have gotten no tips on how to fly with my dog. I think if you take a non dog owner's perspective, it makes a lot of sense. O, people are afraid of pats alurgic yes. Sincidents. Pepler, i fear. And they're dependent on you as the entire points, i just be nice to them and just love them back. Can we get that for people in general?
