Its not like Sydney needs to use her force field orb. Her air orb can create a bubble around her on its own. That leaves her with a free hand to fly or shoot.
(its seen in comic 541)

The other way around might make more sense though, hold the force field orb continuously, refresh the air when needed (I'm assuming the orb has some build in thing against overpressurizing, like absorbing the used air, but if not she can just grow her bubble to fit) and at all other times use the fly orb in that hand. That way she can transport other people. If she has someone in their with flight powers of their own the ride will be even smoother.
