We are travelling to Shanghai late April and then want to connect to Wuhan upon arrival. I will only know my arrival date/time into Shanghai at the last minute so I can't book a flight to Wuhan in advance. Is it possible to buy 2 tickets to Wuhan at the airport once I arrive or should I book 2 seats for a date and change them once we do arrive depending on schedules/times. etc. I think we would be getting in Shanghai late in the afternoon on either April 26 or April 27 and want to go to Wuhan as soon as possible. Thank you.
