Resolutions 300/301 were introduced decades ago to define basic worldwide baggage standards based on default baggage allowances by weight or piece. This simplified standard approach to defining baggage allowances and related charges was out of date, especially for interline.
More and more airlines are defining their own baggage allowances and charges depending on the number of bags checked, class of travel, routings, etc. Regulators found that the old standards infringed on competition laws and a more transparent and automated process was necessary.
Resolutions 300/301 expired on 31 March 2011. The new market oriented carrier based baggage rules came into force on 1 April 2011 with Resolution 302. Resolution 302 defines a methodology to determine which carrier’s rules apply at any given itinerary.
The adoption of resolution 302 was too complex to be manually handled correctly. The Board mandated IATA in June 2010 to mobilize the industry with the goal of automating baggage rules by 1 April 2011. The Airline Tariff Publishing Company (ATPCO) developed the centralized database needed where airlines electronically filed their own baggage allowance policies. To be successful, the ATPCO solution needs to be embedded within reservations, pricing and ticketing systems and interfaced at check-in level.
