Oh, goodness... Where to start? I would love to travel - I'd fly somewhere exotic that I've never been able to see before. Maybe Turkey or Indonesia... I would also love to use my ability to fly to do something useful for someone else. (Of course, my dad would try and convince me to use it to clean the gutters without a ladder or something... haha!)
Flying signifies the ability to change a situation with focus and strategy. Your desire to be free, live spontaneous and select your environment to land are key to answering a lot of inner queries you may have. First of all I would have flied over buildings and soar like birds.
Right now that superpower is so needed. I'd fly somewhere tropical and gorgeous, like Rarotonga, and do absolutely nothing but relax. I mean no tourism or giddy stuff; just freeing my mind of 'stuff' and enjoying myself again.
