In the last few days, I paid $25 each way on a roundtrip from Orient to restaurant in Simpson bay and $35 one way from Orient to Airport with the same cabbie. I didn't quibble even though it was about the same distance. During the roundtrip, I know he went home to French Quarter for dinner and drove back to pick us up, while the run to the airport he was heading to catch the ships coming in after dropping us off around 7am. So, there you have a datapoint range to expect.
