Never tried the bracelet, but the more subtle things like a light meal before flying, staying well hydrated, dramamine(isn't that the seasickness remedy?) seem to help. I rarely get queasy unless doing aerobatics, and then, even after landing, I continue to feel nauseous for hours afterward. Maybe occupy her mind by letting her fly the plane or take photos?

There is also a prescription drug called Phenegren (sp?) that is specifically made for anti-nausea. Side effect: drowsiness.
