I once travelled a couple hundred miles to meet up with a guy I'd been chatting with and developing a connection. I had friends who lived in a town nearby, so I went to visit them, and took a side trip to get together with him. It seemed to go well at the time, as far I could tell... just dinner, drinks, conversation. But after we parted company, there was nothing. Future attempts at contact were met with indifference at best. I was bummed. So now, I would say the connection would have be very strong indeed before I planned travel of any significant distance. If the spark were there, then yes, of course, but it would just take more time to establish that on my part.
