Ask where he’s from
There’s nothing more disappointing than making a great connection with someone only to find out they live on the other side of the country. And the odds of that are high when you’re on a plane! Ask from the beginning where your cute seatmate is from. If he’s from the same place as you, keep flirting! If he’s from far away, avoid the temptation to flirt and chat the whole time. You’ll only be sad when the flight’s over.
