I should point out to expand on my previous post that this larger issue isn't limited to simple mistakes on air ticket or hotel rates and goes much farther.
Take for example my home province sports book operation that goofed in the over/under predictions a while back and, thanks to the spped of the internet, word quickly spread that the numbers seemed so low on NBA games that everybody who wagered and played would likely win. Sure enough, that's exactly what happened on two consecutive nights. Seeing as there are many provincial laws governing this area, the lottery folks had to swallow and pay out a few million dollars to all ticketholders. But a valuable lesson was learned.
Many companies seem to view the internet as the goose that lays golden eggs, but don't want to admit or accept that occasionally that goose will on rare occasions also produce goose droppings. I wish more would step up and clearly take responsibility for the odd mistake and write it off as a cost of doing business on the web.
