7  A reporting carrier must use this form to report on-tim e performance data if: (1) the originally sched uled 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 origina lly scheduled codeshare flight or the substitute codeshare flight; and (4) the substitute flight was an extra section flight or the carrier that operated the flight is not a reporting carrier.
8  For the purposes of fields G, H, J, and K, a carrier must provide information as it relates to the originally scheduled flight that was not operated and subject to the Codeshare Swap and must apply that infomiation in calculating the other fields that are based on the information in fields G, H, J, and K (i.e. M, N, 0, Q, R, S). A ll other fields and references to them relate to the substitute flight that was actually operated.
