Airline pricing blunders lead to massive discounts on business class tickets.

All Nippon Airways mistakenly underpriced some first- and business-class flights due to a currency conversion error on its Vietnamese website. A man from Hong Kong, who runs a travel website, bought 25 tickets worth $250,000 for just $17,000, including a first-class round-trip from Jakarta to Aruba via Tokyo and New York that cost just $890, or a discount of close to 95%. Other passengers also took advantage of the mistake, with one person buying a business-class ticket from Jakarta to New York for just $300. The airline said the tickets were sold cheaply in error and has since corrected the mistake.
