9  A reporting carrier must use this form to report on-time performance data if: (1) the originally scheduled flight was a codeshare flight held out to the public with only one U.S. carrier designator code (that a flight is also held out under any number of foreign carrier designator codes is irrelevant to determining whether to report); (2) there was a flight substitution (Codeshare Swap); (3) the reporting carrier marketed the originally scheduled codeshare flight but did not operate the originally scheduled codeshare flight or the substitute codeshare flight; (4) the substitute flight was not an extra section flight; and (5) the substitute flight was operated by a reporting carrier.
10  For fields G and J, a carrier must provide information as it relates to the originally scheduled flight that was not operated and subject to the Codeshare Swap. All other fields relate to the substitute flight that was actually operated.
