Sandy Valdivieso, 31, said she and her husband, Triet Vo, 39, were going to visit a former colleague of hers in Dakar and realized a few hours after the second leg of their journey began in Istanbul, Turkey, that the plane was headed to Dhaka, in Asia, rather than the African city they intended to visit, the Los Angeles Times reported Tuesday.
The airline sent the couple back to Istanbul and on to Dakar free of charge.
Valdivieso said the mix-up must have occurred when she bought her tickets. She said she and her husband didn't realize the airport code on the tickets, DAC, was for Dhaka. Valdivieso also said they thought the flight attendants were just speaking with accents when they announced the flight's intended destination.
Fatma Yuceler, general manager of Turkish Airlines' West Coast operations, apologized for the incident.
"We are very, very sorry that this happened," she said.
She said the couple will receive two free economy-class tickets to anywhere the carrier flies.
Yuceler said employees are receiving extra training to prevent future occurrences.
