Invasion of Personal Space is a sign of flirting, right? Like Legs crossing into your personal space?

Well, I was on a plane with a guy I go to college with on a flight to North Carolina. We had a really good time, we laughed, talked about life, etc. Later on he asked me if he could splay his legs/feet into my foot space. I was holding my legs on the chair to begin with so I said sure. He then said if I wanted I could put my legs on top of his too if I'd be more comfortable. Is it just me or was that a sign of attraction/flirting? Also, I remember I was cold on the plane and he offered me his jacket but I said it was fine... Guys, what do you think?
