I need to fly from Hong Kong to Chengdu in April. I called a travel
agency here and they said my best bet is to buy a ticket in china.
Buying in the US the tickets are at least $325 one-way. I will be
arriving in Hong Kong 2 days before I need to fly to chengdu. My
questions - is it safe to wait until I get to hong kong to buy the
ticket (given only 2 days advance purchase), and how much should I
expect to pay?

Thanks much!
