Here are a few of the acronyms we use around the airport: CSM = Customer Service Manager CSS = Customer Service Supervisor ETA = Estimated Time of Arrival ETD = Estimated Time of Departure FLIFO = Flight Information HK = Held and Confirmed (This is a reservation code to show that an itinerary is confirmed.) MRO = Manager Ramp and Ops MX = Maintenance NOOP = Not operating PAX = Passenger PNR = Passenger Name Record (also known as confirmation number) SB = Standby UM = Unaccompanied Minor ..... just to name a few......Do you have any to add to the list?
