My first time posting. I will be flying United IAD to CDG arrival 6:55 am. I wanted to book Air France CDG to NAP 9:15 am flight, because it is a non stop. If I miss it they have one at 8:45pm, will they rebook me? Anyone with the same experience? Is this enough time to get through passport control and getting re ticked at Air France? If I fly United business class will that help me get through faster? Tia
