United Airlines customers with reward miles were able to book tickets over the weekend to Hong Kong for only four miles, plus taxes and fees, because of a programing error, according to the airline.
A round-trip flight from Los Angeles to Hong Kong typically starts around $1,800 or 60,000 reward miles under the MileagePlus reward program.
But because of a programing error, some United passengers who booked flights to, from or through Hong Kong were charged only four miles plus taxes and fees, which amount to about $35.
United's online system did not advertise tickets to Hong Kong for four miles. Passengers who clicked on the online system to book a flight but had insufficient reward miles were charged only four miles. Over the weekend, news of the glitch spread on the Internet, prompting many MileagePlus members -- United wouldn't say how many -- to book tickets.
