I am trying to book a SCL-EZE/AEP-IPC flight and orbitz and cheaptickets both price it out for me, but when I go to click on the particular flights to but them, I get messages that they can't be confirmed. Lan.com prices the flights much, much higher. I called cheaptickets CS and was told they can't get LAN to confirm the flights and that's why they can't be booked. Ugh. Is this waiting until tomorrow or Monday to see if they become available? Has this happened to anyone else before?
