Does anyone know if a Part135 charter brokerage company can purchase a group of passenger tickets on an US scheduled operator and add a service fee to the customer? I am not chartering the entire aircraft this time. I am purchasing 103 seat for a group and disclosing to them I am charging them a fee to organize the flight needs. They do not have enough funds to charter the aircraft, only for the needed seats. The operator says no problem..
My question is - Can I legally do this? This is uncharted water for me.
