Glitch sees United Airlines flights to US sold for song
United Airlines has cancelled thousands of transatlantic bookings made by flyers who thought they had bagged the bargain of the century.
For a few hours on Wednesday, the US airline's Danish website was selling first and business-class return flights from the UK to New York and California for less than £50.
It blamed the problem on "an error a third-party software provider made when it applied an incorrect exchange rate".
Buyers who set their country of origin as Denmark were able to book seats at a fraction of normal fares, typically £5,000 for a business-class return from Heathrow to New York, or £7,000 to Los Angeles.
After fixing the fault, it said it was voiding the bookings of "several thousand people attempting to take advantage of an error".
It added: "Most of these bookings were for travel originating in the UK, and the level of bookings made with Danish kroner as the local currency was significantly higher than normal during the limited period customers made these bookings."
