How to write a delay notice for flight delays due to traffic control

Normal flow control generally has an estimated time, and the crew will decide the passenger boarding time based on the situation. However, if you encounter air traffic control, the time cannot be estimated and the control may be lifted at any time, which requires the aircraft to prepare for takeoff in advance. If the waiting time has been long and no clear departure information has been received from the air traffic control department, the crew may ask the passengers to get off the plane and wait in the terminal for the comfort of the passengers. In addition, when some unexpected situations occur in the air or at the destination airport, passengers may be forced to slide back to wait when the plane is about to take off.
