I am flying out next Monday on a charter flight out of O'Hare and was wondering if anyone can give me some insights on the process. Frontier charges more if you wait to pay for baggage when you get to the airport but during the booking process I was unable to pre-pay for this like I would have been able to on a normal flight. It also looks like they are charging for "Carry on" luggage and only allow you to bring a personal item. Is this still the case? I do not want to get to the airport and find out that I am paying another $100 to get on the plane.
