The Department of Transportation (the Department) is extending until July 18, 2005, the period for interested persons to submit comments on the February 14, 2005 NPRM published in the Federal Register on February 17, 2005 (70 FR 8140). In the NPRM, the Department proposed to revise the rules governing the nature, scope, source, and means for collecting and processing aviation traffic data. Those reporting requirements are known as the: Origin—Destination Survey of Airline Passenger Traffic (O&D Survey); and Form 41, Schedule T-100—U.S. Air Carrier Traffic and Capacity Data by Nonstop Segment and On-flight Market and Form 41, Schedule T-100(f)—Foreign Air Carrier Traffic Data by Nonstop Segment and On-flight Market (collectively, the T-100/T-100(f)). Current traffic statistics no longer adequately measure the size, scope and strength of the air travel industry. This NPRM proposes to simplify the requirements placed upon Carriers reporting the O&D Survey. The proposed changes to the O&D Survey would eliminate the ambiguity in the identification of the Participating Carrier and eliminate the need for manual collection processes by designating the Issuing Carrier as the Participating Carrier. It would also increase accuracy by expanding the volume of data to 100 percent of Ticketed Itineraries, thus making the data more useful by collecting broader information about the Ticketed Itinerary sale and the scheduled itinerary details. The changes to the T-100/T-100(f) being considered, would improve the quality of the data by maximizing the congruence of the O&D Survey and the T-100/T-100(f).

On April 1, 2005, the Air Transport Association of America, Inc. (ATA) filed a motion (OST-1998-4043-71) requesting a 90 day extension of the date on which comments related to the NPRM are due. On April 4, 2005, the Airlines Reporting Corporation (ARC) filed a request (OST-1998-4043-72) for 90 day extension of the comment period and supported the request of ATA. In its answer (OST-1998-4043-73) filed on April 5, 2005, the Airline Tariff Publishing Company supported the motion of ATA for a 90 day extension of the comment period. On behalf of its 47 members, the Regional Airline Association (RAA) filed an answer (OST-1998-4043-74) on April 6, 2005, supporting ATA's motion for a 90 day extension of the comment period. On April 7, 2005, the Airports Council International—North America (ACI-NA) filed an answer (OST-1998-4043-75) supporting ATA's motion for a 90 day extension of the comment period. American Airlines, Inc. (AA) filed its own motion (OST-1998-4043-76) on April 7, 2005, also requesting a 90 day extension of the comment period.

In their motions, both ATA and AA discussed the length and complexity of the NPRM and the need for affected parties to understand and evaluate the implications of the proposed rulemaking. ATA noted that this rulemaking is likely to be a “once-in-a-generation” undertaking and that “such a comprehensive reexamination of air Start Printed Page 20099carrier reporting requirements will not recur for a long time.”

RAA observed that “[t]he length and complexity of the NPRM require more time for a proper analysis of the proposal” and ATPCO asserted that “[a] 90 day extension is reasonable given the scope of the suggested changes and the need for careful consideration of implications of those changes prior to the submission of comments on the NPRM.” ACI-NA agreed, stating that “granting ATA's motion would give DOT a more extensive, thorough and considered record on which to base its decisions without unduly delaying the rulemaking process.” ARC noted that “an extension will enable the parties to submit comments that more fully respond to the NPRM but will not unduly delay the rulemaking process.”

Because it appears that an extension of the comment period to allow additional time for commenters to address the proposals in the NPRM would be beneficial and in the public interest, we are allowing an additional 90 days for submission of comments, which should be sufficient to accommodate commenters' need for additional time.
