Pros: Nothing, it was extremely annoying.
Cons: Because of the two hour delay, I was going to miss my next flight. I told the flight attendant about my problem. She said that it would be fine, and they would help me once I landed. That didn't occur. I got through customs and rushed to the airline desk. They then told my that my connection flight had been delayed. I went through security, and I sat next to my gate. For hours it said delayed, but didn't give a new time. I asked the staff, and they said later. After four hours, I asked again, and they told me that the flight had left. I asked another staff member, who told me that the flight had been canceled, and I needed to get a new ticket. I never got an answer as to whether the flight had been canceled, but I was not going to leave Xi'an that day. They sent me to a hotel, which was more than 20 minutes away from the airport. In the morning, the airport transport was late, which caused even more stress. To top all of this off, I had to go to three different people for my ticket because there was some unknown problem.
