A similar journey in first-class via Frankfurt meanwhile, would set travellers back an eye-watering $16,000. "We are looking into the root cause of this incident both internally and externally with our vendors," a Cathay spokesperson, who attributed the error to an "input issue", was cited as saying.
The Hong Kong-based carrier will honour the cheap fares for the "very small number" of savvy and fortunate travellers, the spokesperson added, as it did last time. Cathay did not immediately respond to AFP's request for comment. Airline and travel blogs went into overdrive on New Year's Eve after eagle-eyed shoppers noticed the carrier was offering first and business class tickets on its website from Vietnam to the United States and Canada for as little as $670.
