APPLICATION FOR EXPANDED EXEMPTION FROM FILING AND APPROVAL OF AGREEMENTS

Pursuant to statements submitted by Member airlines of the International Air Transport Association (IATA), 

the undersigned has been constituted to be their attorney-in-fact for filing with the Department of Transportation 

copies of agreements adopted by the IATA Traffic Conferences. 

On their behalf, and pursuant to Sections 40109(c), 41308 and 41309 of Title 49 of the United States Code 

and Sections 302.4, 302.302, 303.03, 303.05 and 303.30(c) of Title 14 of the Code of Federal Regulations, I am filing 

with the Department this application for an amendment to the exemption from condition #2 granted by Order 2006-12-

4 (2 January 2007) and expanded by subsequent Orders. The present application requests that such exemption be 

further expanded. The subject agreements and related factual and explanatory material and documentation required 

by 14 C.F.R. 303.31 and Department and Civil Aeronautics Board (CAB) precedent accompany this application. 

 The subject agreements are IATA Resolutions that together establish the procedures for establishing 

passenger Flex Fares on routes between TC31 North & Central Pacific (between Korea (Rep. of), Malaysia 

and USA). What is submitted for review and exemption is a process and algorithm for defining fully flexible fare 

products for first class, business class and economy class travel as well as restricted economy class travel on certain 

routes within these markets. 

Prior Department rulings provide the context and precedent for the present request. By Order 2006-12-24, 

the Department exempted the Resolutions establishing the Flex Fares system for establishing IATA interline fares 

within the European Common Aviation Area (ECAA), future amendments to those Resolutions, and fares generated 

under the Resolutions from condition #2 imposed on the Provisions for the Conduct of the IATA Traffic Conferences, 

provided that the Resolutions and amendments thereto are limited to the establishment of fares for travel within the 

ECAA. IATA subsequently has adopted Resolutions expanding the Flex Fares system to include many other regions. 

Orders 2007-9-16 (14 September 2007), 2008-4-45 (5 May 2008), 2008-7-24 (28 July 2008), 2008-11-20 (2 

December 2008), and 2009-10-9 (22 October 2009) expanded the exemption from filing granted by Order 2006-12-24 

to cover other Resolutions providing for such Flex Fares in non-U.S. markets, on the ground that fares for travel 

within those regions typically present no public interest concerns justifying the Department’s pre-implementation 

review of agreements limited to such travel. Orders 2008-7-4 (7 July 2008) and 2010-5-5 (7 May 2010) similarly 

exempted Resolutions providing for Flex Fares in specified U.S. markets, on the grounds that the Flex Fares system 

is a computer-driven process that involves no direct contact between carriers and that other interline fares are 

expected to be available in those markets. 
IATA requests further expansion of the exemptions granted by those Orders. The reasons justifying the 

present request for expansion of the exemption to include the subject Flex Fares Resolutions, future amendments to 

those Resolutions, and fares generated under the Resolutions are the same as relied on by those Orders with 

respect to prior Flex Fares agreements. 

These agreements arise from the continuing process of Tariff Coordinating Conferences and were 

developed in the context of prior Department and CAB rulings addressing related resolutions which reflected 

regulatory and market conditions then in effect. Thus, the present agreements should be viewed as part of a dynamic 

process of IATA Member airline adjustment to governmental and economic factors. Therefore, granting the requested 

expanded exemption would serve the public interest, and thus, meets the Section 40109(c) standards for exemptions 

from filing and approval requirements. 

Respectfully submitted
