H and I are going to the east coast except I am heading to NY and H is going to North Carolina. We've talked about our trips for the last few months. We booked our flights separately and never showed the other person any flight schedules
3 weeks before the flight
Me: I'm leaving on Friday (whatever the date was) too, what time is your flight?
H: 11
Me: mine is at noon but I can go early so we can go together
Week of the flight
Me: what airline are you flying?
H: American airline. My flight is actually 11:55 so it's closer to yours.
Day of the flight
H: my layover is in Texas
Me: oh mine is in Dallas... Wait.
H and me in unison: Are we on the same flight???
The answer was yes.
Is it serendipity or simply poor communication? Who knows but it turns out that I had an empty seat next to me so I was able to sit with a homie for the first leg of the flight instead of flying solo.
