There are several ways to book flights in Korea. Reservations can be made on the airline's website or through a travel agent. You can also use ticket price comparison sites to compare ticket prices from different airlines before making a reservation.
How to book a flight on the Korean Airline website
First, you need to access the Korean Airline website and register as a member.
Then select "Book Ticket" or "Make Reservation". Enter the starting point and destination.
Enter the departure and arrival dates. Select the number of passengers and class of seat. If you have additional checked baggage, you must add KG including your own baggage. In the case of checked baggage, it becomes more expensive if added at the airport. If you choose your options well in advance, you won't have to pay extra and you won't have to pay an unexpected amount. Check the ticket price and complete your reservation. After completing the reservation, you must carefully read and enter your English name or passport number.
The advantage of doing it directly with the airline is that there are no commissions paid to the travel agent. However, there is a downside that you have to find out about the consignments and additional options yourself and choose well.
