well I cant say that flying triggers mania but it does trigger psychosis for me while on the plane. my pdoc gives me Haldol to take for the flight to stabilize me so I can make it across time zones. anything over two hours triggers it. I flew to japan, that was thirteen hours and I watched movies the whole flight to keep me distracted and that seemed to work. I was already manic at the time. hope you find something that works. take care.
