Lift needed to Carcassonne airport on Friday 26th September from Castres area

Morning all

Short notice I know but just on the off chance that anyone else is catching a flight to Carcassone on Friday and has 2 spare seats and room for 2 small cases. Our flight is 3:20 but willing to go any time and obviously pay expenses.

Does anyone know if there is a bus from Castres to Carcassonne?

Thank you
