I found some good fares on EF just 15 minutes ago for travel from SCL to both LAX and DFW in the next weeks, and they are substantially lower than what shows on AA.com. I called the EXP desk and she gave me the same fares on aa.com, even though I told her that I have the fare basis codes. What can I do to book these fares? They are valid for my trip - dates, routing, min/max stay, etc. Just noted that the same fares do not appear on ITA, but I don't know how trustworthy that is anymore... Thanks!
