Pros: Standard flight

Cons: My connecting flights were terrible. I was kept at the airport on a layover to another city and they wouldn't let me board because they said my passport number was entered wrong on the reservation. This made no sense as I had gotten off another flight on my way back home. No one at the airport in Shanghai was helpful and it was really frustrating to think that I would be stuck in China. I was finally able to track down a international supervisor who was able to print out my boarding passes and let me board my flight. Unfortunately, another family with small kids were dealing with the same issue as me only their flight was leaving in 30 mins. I hope they were able to make their flight.
