So, to the extent anyone's interested, as mentioned above, we ticketed this in Canada in late May to take advantage of the Canadian pricing exception. This was the final routing: CJC-xSCL-IPC-SCL-EZE-JFK//LGA-xDFW-OGG//HNL-NRT//KIX-BKK//DPS-HKG-LHR-MRU//NBO-xLHR-xJFK-SCL. Our flight into South America is on a one-way BA award on LAN (40,000 BA miles/pp. for OW in business class). We'll book our OW return from SCL at the end of the trip (too soon to book those seats for Oct. 2009).

The interesting thing here is the SCL-EZE flight. I had initially had this reserved (prior to ticketing) as an open-jaw (SCL//EZE), but then replaced it with a flight at the last minute (as seen above). (Our RTW trip has lots of intra-South American travel, and SCL-EZE was a leg I was going to have to purchase anyway.) I couldn't figure out why I hadn't realized earlier that I should book SCL-EZE as part of my DONE5, rather than buying it as part of the LAN South American pass.

The answer, as I recently realized, is that I only get two stopovers on the continent (not the country, as I had supposed) of origin. The not-so interesting fact is that I didn't spot this error. The more interesting fact is that AA's rate desk didn't spot it, and the flights were paper-ticketed as above. The tickets were then re-issued in the U.S. because of the incorrect taxes I was charged, and again, no one spotted (or looked for) the error. I then changed the date of this flight based on some changes in my connecting LAN flights. Again, no problem. I then tried to change the date a second time because of still further LAN schedule changes to our connecting flight, and this time the AA agent pointed out that (1) I had three stopovers in my continent of origin, and (2) I'm not allowed to change the date for my first international flight. Ultimately, AA let me change the date (perhaps because it had already been changed once), but said I wouldn't be allowed to do it again, and that my PNR would be noted that I had now been advised to that effect. The tickets have already been issued, and AA said they wouldn't seek to cancel them or anything like that (notwithstanding the extra stopver in South America). All very odd (and surprising, since this wasn't some sort of secret plan of mine to skirt the rules).
