My father is coming nex month

Today I find out that my father is coming to the USA some day in the middle of the next month. He has not booked the flight yet. I admit the surprise. I was expecting my mom to came, but she told me that my father putted pressure on her to changed her mind and make he to stay. Anyway, I am excited about my father. He has never had flown on a plane before. He worries about the whole trip because this is new for him. Probably he will be looking a little longer to find the right gate at the airport. I hope he will not get lost at the airport. Perhaps I am going to write down on a piece of paper that he is flying by himself and he does not speak English at all. I have not figure it out yet.
