Flexibility for operators is a Key Performance Area (KPA) for Air Traffic Management (ATM). This paper presents a framework for development of operator flexibility metrics, with a first test-case application to management of departure queues. Through the use of virtual queuing (VQ) in departure operations, operators are provided with additional flexibility in prioritizing flights for departure. VQ allows flights whose delays are more expensive to skip ahead in the departure queue, while other flights with less expensive delays move back.
