Definitely wings. First thing I thought of. Unfortunately that would require a massive redesign. Firstly, you'd need hollow bones, as well as a very low body fat percentage. Decent chance boobs and butt don't grow hardly at all. Secondly, you'd need extremely strong chest muscles, which also still have to be light. And in order to provide enough energy for that, you'd need a larger and stronger heart with wider blood vessels. You'd also need to most likely quintuple your daily calorie intake. Possibly more depending on how often/when/ where you are flying. You would also want lungs with more surface area to absorb oxygen better, even at low altitudes. Especially at higher altitudes. That would likely mean a stronger diaphram. Stronger leg muscles for takeoff/landing. Better eyes for scoping out landing points and avoiding hazards. Most birds don't fly at night, so you may consider something akin to a cats eyes, or go the bat route with echolocation. And you're going to need a neutral remapping unless you just plan to replace your arms with the wings. Fortunately, outside of a higher energy cost, that last one might happen automatically, our brains are very plastic.
