IATA develops and maintains Common Use standards including a Resolution and Recommended Practices through the work of the Common Use Group (CUG).

The CUG deals with matters concerning:


  • Common Use Self Service (CUSS), the specifications and standards for multiple airlines sharing one physical self-service kiosk. (RP1706c). 
  • Common Use Passenger Processing Systems (CUPPS), the range of services, specifications and standards enacted to enable multiple airlines, service providers or other users to share physical check-in or gate podium positions whether simultaneously or consecutively. (RP1797)
  • Bar Coded Boarding Pass (BCBP), the required characteristics of the data elements and format of the Bar Code on the Boarding Pass. (RESO 792)
  • Common Use Web Services (CUWS), the standardization of data exchange supporting common use self-service bag drop and different touchpoints through the use of web services technology. (RP 1741)
  • IATA Technical Peripheral Specifications (formerly AEA) (ITPS-TSG), the maintenance of the specification that describes all exchanges of Departure Control Systems (DCS) to device communication and all device responses supporting Boarding Pass Printer (ATB), Baggage Tag Printers (BTP), Boarding Gate Readers and Self-Boarding Gates (BGR and E-Gates), SBD (Self-Baggage Drop) and SD (Scale Device)
  • Review and endorse proposals to create or amend standards governing these processes, including data exchange standards for passenger data
  • To liaise closely with other bodies, including Airports Council International (ACI) and IATA Committees impacting on Common Use Standards

How are Common Use standards created?


Standards endorsed by a majority vote will be presented to the Travel Standards Board for approval, before presentation to the Passenger Services Conference (PSC) for adoption as required.

Changes to data exchange standards require endorsement by the Architecture and Technology Strategy Board under the provisions of Resolution 009.

Change to any other Resolution or Recommended Practice requires endorsement by the owning group and adoption at the Conference as required.

This brochure (pdf) outlines the Conference structure as well as standards adoption and development procedures.

The Common Use Group does not restrict its number of participants and is opened to:

  • IATA Member Airlines
  •  Airports
  •  Governments
  • Strategic Partners participating in the Strategic Partnerships program with the industry area of involvement of Passenger Experience or Common Use
