{"abstract":"As required by Federal statute, the Department of Transportation is modifying certain reporting requirements. We are requiring air carriers that file airline service quality performance reports to collect and report the causes of airline delays and cancellations. Currently, there is a lack of data on the specific causes of airline delays and cancellations. The changes are designed to fill the data gaps in reference to the causes of airline delays and cancellations and to provide this information to the public and other interested parties.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Office of the Secretary"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2002/11/25/02-29910.html","cfr_references":[{"chapter":null,"citation_url":null,"part":234,"title":14}],"citation":"67 FR 70535","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on June 1, 2003.","disposition_notes":null,"docket_ids":["Docket No. OST 2000-8164"],"dockets":[],"document_number":"02-29910","effective_on":"2003-06-01","end_page":70545,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/11/25/02-29910.xml","html_url":"https://www.federalregister.gov/documents/2002/11/25/02-29910/reporting-the-causes-of-airline-delays-and-cancellations","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/02-29910?publication_date=2002-11-25","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-11-25/02-29910/mods.xml","not_received_for_publication":null,"page_length":11,"page_views":{"count":827,"last_updated":"2026-10-24 10:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-11-25/pdf/02-29910.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-11-25","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/11/25/02-29910.txt","regulation_id_number_info":{"2139-AA09":{"issue":"200304","html_url":"https://www.federalregister.gov/regulations/2139-AA09/amendment-to-part-234-to-collect-causal-information-for-airline-delays-and-cancellations","title":"Amendment to Part 234 To Collect Causal Information for Airline Delays and Cancellations","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200304&RIN=2139-AA09&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2139-AA09"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":70535,"subtype":null,"title":"Reporting the Causes of Airline Delays and Cancellations","toc_doc":"Causes of airline delays and cancellations; reporting requirements modifications","toc_subject":"Airline service quality performance reports:","topics":["Advertising","Air carriers","Consumer protection"],"type":"Rule","volume":67}
