Flying with Firefly - and no caster wheel

Hi! Unfortunately a repair got delayed, and now I have to fly home from college in this situation. I’ve used my chair always hooked up to the firefly since my left caster took damage in a fall a few weeks ago - a temporary fix since I really hated the only rental available to me. This is my first time flying with the firefly in general (I got it specifically for college) so I’m extra wary about damage. The wheel is fully removed from the frame to prevent further damage, so my chair can’t stand upright on its own without the firefly attached. In any other situation I’d gate check the chair and in-cabin store the u-bar and battery separate from the rest, but I’d love if anyone else had some ideas of how to make it as easy as possible in the airport with minimal damage risk in this scenario. Thanks!
