A trip halfway around the world for the low price of four reward miles ended up being too good to be true for some United Airlines customers Friday.
A programming error allowed United Mileage Plus members the opportunity over the weekend to purchase flights from or through Hong Kong for four miles plus taxes and fees, which totals to $35, according to a Chicago Tribune report.
Normally prices for flights to Hong Kong start around $2,000 or 60,000 reward miles.
United cancelled all the unused tickets that had been purchased for four miles.
That cancellation is prompting the Department of Transportation to investigate, because a federal regulation prohibits airlines from increasing fares after tickets have been booked, the Tribune reports.
A United spokesman told the paper he does not believe the airline violated the regulations, and that "We think we will get a fair outcome with the DOT."
