A group of happy passengers, Kate Pasifik, "won" tickets in the first class at an economic price, the second time this month.
Hong Kong tickets to Portugal were offered Sunday through the company's website at a price of 1,512 dollars, instead of 16,000, which is the right price for this flight.
Although the investigation is under way, the company has announced that passengers who bought these tickets will still travel first class.
This error occurs after the company has recently misused personal information.
The longest flight without stopping
The plane hit the wall when it landed
The flights from Lisbon to Hong Kong, through London, were offered at a price of 1,512 dollars, reports the South Tea Daily newspaper.
The same flight with a transfer to Frankfurt costs $ 16,000.
A Hong Kong-based company said that passengers who travel to cheaper tickets would travel to the first class.
"We are currently investigating the cause of this failure internally and externally in cooperation with entry sellers," the statement said.
"For travelers that have bought these tickets, we would like to welcome you and hope you enjoy our top quality services."
A similar failure occurred two weeks ago.
The lucky ones could travel from Vietnam to New York and return for $ 675 in a business class. These cards also cost 16,000.
And then the company admitted the error, but the passengers traveled to the business class.
Companies sometimes leave travelers with cheaper banknotes in the first class, and sometimes they do not.
For example, Singapore Airlines has allowed travelers to buy low-price tickets in the first class of 2014. Ericsson Airlines canceled airline tickets to the foreigner, that were sold for less than $ 100.
Year full of challenges
This failure is just one of the wrong moves the company recently launched.
In October, information systems were mistreated in the company, thus compromising the data of 9.4 million passengers.
A month earlier, one of the planes had to return to the painting workshop after the name of the company had not been written correctly on the plane.
These failures occurred while the company was trying to make it profitable, since last year it registered losses for the first time in March.
Kate Pasifik has a great deal of competition, the most threatened being low-income Chinese companies operating in Hong Kong, China and all Southeast Asia.
