Skylux travel이란 사이트를 통해서 대한항공 비즈니스 티켓을 샀습니다. 리턴 날짜를 한달 미뤘는데 아래와 같은 답변이 오면서 택스를 더 내야한다고 하네요. 이전에도 비슷한 변경을 했었는데요 그때는 안냈었거든요. 담당자가 바뀌니 좀 믿음이 덜가서요 이런 경우가 있으신가요
Please be informed that all the airline bookings, except the the traditional classes of service, are also based on the booking class availability. Your original booking has been made in booking class " O " - so called "Reservation Booking Designator". By the specific fare rules applicable to your reservation contract the change of RBD to a higher one leads to change of the total taxes price. In your specific case the new taxes price will be $237.00 higher.
