Ask HN: Forgo meeting a team in person for a new job?

I'm considering a Software Engineering role at a startup that is across the country from where I am currently located. All my interviews and conversations have been by phone, and their team is semi-distributed. I would be relocating to their office if I took the job (I want to do this).

I've got a good vibe from everyone I've talked to so far, I believe in their business model, they've been open about their numbers, etc. However, I feel nervous about saying yes to this offer having never met anyone in person. I'm going to ask for them to fly me out to meet people in person before I say yes, but plane flights to this location, from mine, are super expensive (1.2k+), so I don't think I would hold it against them if they refused to fly me out just to see their office and meet some folks for a day.

What are people's thoughts on the matter? Has anyone said yes to something like this before? Did it work out? What are some things I should be aware of, maybe I can ask some questions to make up for the lack of in person check?
