Call it a nightmare that hopefully, only a few unfortunate travellers will ever experience - if at all.
A woman in Taiwan managed to fly to Hong Kong, not only on the wrong airline, but under the name of a male passenger with the same surname as her.
In the bizarre incident which took place in early February, the Taiwan resident who was only identified as Ms Hong, 34, arrived at Taoyuan Airport to board her flight to Hong Kong.
Her boyfriend had earlier booked a round-trip on Hong Kong Airlines for her.
But at the airport, Ms Hong instead went to the Cathay Pacific kiosk to check in, reported the South China Morning Post.
At the counter, the employee handed her a boarding pass rightfully intended for a male passenger who happened to have the same last name as her.
She managed to get on the Cathay Pacific flight and landed safely in Hong Kong without being stopped by ground staff or local immigration authorities.
The mistake was only noticed when her boyfriend received an alert from Hong Kong Airlines that she had not boarded the flight. The second leg of a round-trip flight is usually voided if the passenger does not complete the first leg.
Cathay Pacific has since acknowledged the mistake and is investigating the matter while Taiwan's flight boarding procedures have come under question.
Confirming the incident on Friday (Feb 19), a Cathay Pacific spokesman said: "Initial investigations indicated that there was an error in the check-in procedures.
"We take this matter seriously and are in the process of securing more information from the relevant teams and reviewing the check-in procedures on that day to ensure that similar incidents will not happen again."
Ms Hong claims that Cathay Pacific has since coordinated with Hong Kong Airlines to arrange a return flight for her to Taiwan, as well as offered her access to their VIP lounge on her next trip, added the SCMP report.
