Hi all ... I'm planning a trip later this year to the Falkland Islands, and am trying to figure out how to make a mixed-class booking on LAN.com -- MEX-SCL in business, and SCL-PUQ-MPN in economy.

Is there a trick to making a mixed-class booking on LAN.com? Or will I have to call LAN to book my ticket? I've only ever done a single-class ticket with them before, so this is a new issue for me. I've already found the itinerary and pricing I want on Matrix, but have been unable to get the LAN website to cooperate.

Thanks!
