I'm always faintly (only faintly) amused by airline
PR releases like the ones here where an aircraft operated by a codeshare partner, a commuter carrier, or (as in this Pakistan instance) leased in comes to the attention of the press.
The main airline release always starts with the fact that the aircraft belongs to the minor organisation, and gets several additional comments on this in, before saying at the end of the sentence that it was operating the mainstream airline's flight.
The company operating the aircraft always starts by stating the flight number, route, etc of the mainstream airline, and only says at the end that it was their own aircraft.
Each is trying to do a "nothing to do with me" comment. As they often hit the media very rapidly indeed, the texts must be prepared in advance.
