Airline Cancels Passengers’ $10,000 Business Class Tickets Sold in Error for $300

ANA Holdings Inc. canceled flight tickets that were sold in error at a fraction of their usual prices last week, avoiding a hit to its finances but disappointing customers who’d snapped up premium seats ultra-cheaply.

Airfares — including for first-class spots that usually cost thousands of dollars — were listed at deep discounts following a currency conversion error on ANA’s Vietnam website. Opportunists jumped upon the mistake, with one snagging round-trip first-class flights from Jakarta to the Caribbean for $890.
