"Flight of Fateful Coincidence"

Prompt: A 22-year-old first officer on the 777, who has only been flying for one year, gets his first flight. That is the day where he's a passenger, but has to go to a destination from where he'll fly. In that flight, he doesn't use his uniform, neither he was obligated to. And while flying, he sits next to another young man, looking in his 30s or 40s. They get to talking a bit, and slowly and slowly, very slowly, realize they are both into aviation, and that they are both the pilots who'll be flying the next flight by Captain First Officer.
