Many factors play into your question. Flight Altitude, Number of Pax, Head/Tail winds, etc.... I recommend you read the response from citrus jock on the Thread 'Pilot Advice Needed'. That should give you an idea where to start from. Here's an example from a Flight this morning. MCO - ATL - Out @ 0555, In @ 0712 - 112 Pax - Fuel Burn 5800 pounds. This includes Taxi @ both ends of the leg. Hope this helps. B)Does anyone know the appx hourly fuel burn for a AirTran 717? Thx.
