Matt Lauer did a piece on the Today Show this morning (video clip) on the recent spate of travel pricing errors.
He mentions the USAirways $1.98 fare, the $55 Fiji trip, and the Lanesborough Hotel pricing error. He manages to hit key questions like whether airlines and hotels have to honor pricing, what role the internet plays in disseminating mistakes, and whether lists and websites promoting the errors are monitored by travel companies in order to correct errors more quickly.
The piece actually seems to be driving a bit of traffic to this website today. Mentioned in the interview are Flyertalk, FareAlert, and the New York Airfare Blog. Lots of people looking for similar sites are happening onto this one.
