Some Cathay Pacific customers have gained first-class seats at economy prices in the second fare error by the airline this month.
Tickets on flights from Hong Kong to Portugal were sold on the airline’s website for $1,512, instead of $16,000 usually charged for a similar journey, the BBC reported.
The Hong Kong-based carrier said it would honour the tickets as it investigates the cause of the error.
The mis-priced fares were available on Cathay Pacific’s website on Sunday, the BBC reported.
First-class flights from Lisbon to Hong Kong – via London with a connecting flight – were offered for $1,512 (£1,177), according to the South China Morning Post.
A similar first-class journey through Frankfurt would cost $16,000.
In a statement, the Hong Kong carrier said it would honour the tickets.
“We are looking into the root cause of this incident both internally and externally with our vendors,” it said.
“For the very small number of customers who have purchased these tickets, we look forward to welcoming you on board to enjoy our premium services.”
The airline made the same error just two weeks ago when business-class seats on flights from Vietnam to New York were made available for about $675 return.
They should have cost $16,000.
The carrier acknowledged its “mistake” at the time and said it would welcome the passengers on board.
