Flying to Xian - Terra Cotta Warriors

After spending two days in Beijing we had to fly to Xian. Our guide left us in the local airport without any directions. None of us spoke Chinese but suddenly two women came to us and grabbed our bags. They said some thing in Chinese and showed us check in counter. For some reason they didn't stay in line and went directly to the counter. Five minuets later our bags were checked in. We thought Wow! What a service for the foreigners. Two ladies showed us the gate and started to say something in Chinese. One of them showed us some tickets and started to yell - $30 per person. From her reaction we understood that we had to pay them $60. When I asked them Why? The other lady said – overweight bags. I didn't believe them. When my brother asked them for their ID's price went down to $20 and when I mentioned police they took off without any money.
