I'll be travelling from New York to Hong Kong through Shanghai (Pudong) on China Eastern. Originally, my flight had a 1 hour 40 minute layover in Shanghai (Pudong) to make the transfer. Recently, I received an email from Travelocity telling me that my flight from Shanghai (Pudong) to Hong Kong was changed and that I have to call and reschedule. There now is 1 hour and 35 minutes to make the transfer. Is that enough time, or do I really have to reschedule?
