Whether you decide to teach her to fly outside or even inside with the harness on or not is in many way sort of a moot point as it is in my opinion a safety measure more than anything else. You just never know if or when something unexpected might occur that causes her to fly. And as a safety measure it is also recommended that you clip the leash to your body instead of relying on holding it in your hand, so that if something does cause her to fly unexpectantly that you don't inadvertently jerk the leash.
Sounds like you had a great first outing with her and her harness.
