Definitely not correct. The "Airport Construction Fee" (which is essentially Departure tax) is RMB 50 for all domestic flights. Which is a lot more than $1.50. Not sure what it is you are looking at--I assume your ticket was not issued in China, since it is priced in $. Perhaps your airline/agent is just mixing around the various taxes at will and ascribing their own amounts to the different statutory line items?

The fuel charge on domestic Chinese flights has recently been changed to either RMB 80 or RMB 150 depending on distance. That's in addition to the ACF/departure tax. So, assuming your ticket is for a shorter journey, the taxes/fees at current exchange rates would be about $20 of that $96.50 total (I'm assuming USD is the unit). $31 if for a journey over 800 km/480 miles. Maybe those numbers don't look so amusing now...
