No, please do not make duplicate bookings for the same passenger.
We are afraid that we cannot accept your booking if you have multiple reservations on the same/similar itinerary (including package plans/only flight booking) even if the reservation made through another travel agency. Please note that the booking will be cancelled without notice.
The following are examples of duplicate bookings.
・Same section of routes on the same day
・Same section of routes on dates in close proximity to each other bookings
・Different section of routes on the same date
・It is reasonably considered that the guest cannot use all of the seats reserved.
