If we are talking about the same thing, I still say they are full of crap. I saw, booked, and was confirmed on 6 LA flights that I took in A class in April. LAX-SCL-CCS-SCL-LIM-SCL-LAX. My agent uses Worldspan, and there was no issue. They would only release 2 A class seats at one time, though. The only one that was completely blocked was the IPC flight, that I now see is open. Given that it's winter, I will assume that they only open it at this time of year.

Great airline, by the way. Not the best seats, but the food was the best of all the airlines I flew.
