The fast Joci P ⁇ pai of Delta Air Lines is causing a stir among netizens. On the 31st of last month, Hyeri said, "The Planes seat rating I booked a month and a half ago was Downgraded," he said. "I can not afford a Refund, and if I do not like my seat, I get unfair treatment from an external Airliner." "I even booked two seats, but how can both of them be Downgraded?" he said. "I had a lot of things to say, but I couldn't do it properly, so I thought I should study English hard. Please be careful." Then, when the contents gathered the issue, I posted the situation in English with the article "It is not domestic Airline. Please do not misunderstand". Hyeri did not reveal the name of Airline, but some netizens revealed that the Airline was Delta Air Lines through a photo uploaded by Hyeri. Hyeri's previous unfair treatment was not due to overbooking. overbooking refers to the Airline practice of reserving more people than the capacity in preparation for a sudden Planes vacancy caused by Passenger ticket cancellation or change. "In this case, Delta Air Lines will advise the Passenger to fly first class, or to Refund the difference on the seat when boarding Economy Class," Delta Air Lines said on Tuesday. "He said. Delta Air Lines said, "The amount of the difference is being Refunded," he said. "We apologize for the inconvenience to you and the customer service representative will contact you directly." Hyeri declined to comment separately on its subsequent progress with Airline. This is not the first time that Delta Air Lines has been dealt with poorly. Overseas, there have been many cases of controversy due to overbooking, and there have been many cases of large and small inconveniences in Korea. The netizens were surprised by the fast Joci P ⁇ pai of Delta Air Lines and said, "Is it Celebrity?" However, other netizens continued to say, "This should be a public debate." Photo by D.B. Hyeri
