and then appears a timely article on the subject.....

"Flights are sold out for months in advance because of a quirk in travel rules allowing anyone with a valid airline ticket to exchange up to $3,000. The maneuver is known as el raspadito, or the scrape....
"But only if you can secure a seat. The scrape has sent airfares soaring, with the lowest advance-purchase price next month for a return flight from New York currently priced at $2,550 on Aeroméxico. United’s (UAL) nonstop flight from Houston is selling for nearly $4,600 in October, while American Airlines flights from Miami can’t be booked for less than $3,000. Fares on Delta (DAL) from Atlanta in November also top $3,000. As a result of the high level of unused seats, some airlines are beginning to overbook at much higher rates than usual and might add extra flights."
thanks for teeing up the topic, Josh. Turned out to be an education for a lot of us.
