after completing the relevant procedures, you can wait in the corresponding waiting room to rest. If you need service, you can ask the staff for service. Of course, when you hear the broadcast prompt and want to board the plane, a flight attendant will check your boarding pass at the boarding gate. If you want to smoke, there will be a special smoking room. Smoking is forbidden on the plane. After boarding the plane, for the sake of passengers' own safety, we should fasten our seat belts, put away our carry-on luggage and wait for the plane to take off.
