「Advanced Seat Selection」
Although the seat map shows there are some vacant seats, why can't I designate my seat?
Sometimes you cannot designate your seats by following reasons.
・Passengers aged under 15 years old, and passengers who accompany with children, who is under 8 years old offer an emergency exit seat.
・Passengers travelling with infant having seats side by side.
If you cannot designate your seat on the Internet, please offer your seat at the airport counter or the self-service check-in unit at your date of departure.
