I've been chatting on the phone & email/chat to a sweet & incredibly cute Ukrainian Girl?

She wants to come and stay with me for a couple of weeks (so we can get to know each other better) I was waiting for a "can you send me the airfare" as I've heard of this scam! But she only wants me to pick her up at the airport. She is a little old fashioned with old fashioned values (but I like this!) Could this be happy days? Any thoughts on this?
