I have a question regarding the operations of LAN and TACA. Both airlines not only operate in their homecountry any more (Chile and Costa Rica), but throughout Latin America (LAN as LAN Peru and LAN Argentina and TACA with flights e.g. from CCS to LIM). Now my question is: On these flights operated under LAN or TACA-flightnumbers but outside their homecountries who is actually the operating carrier of these flights. Is it still LAN Chile and TACA as a Costa Rican company, or are these flights operated by subsidiaries legally registered in the other countries?
Thank you for your help!
