ANA seat selection: save the choice for each flight
When continuing to another flight sector, ANA offers Register and continue. Merely highlighting a seat on the map is not the stated final saving step. ANA limits the seats offered for advance selection, and some travel-agency or partner bookings cannot use the same service. An unavailable advance map should therefore not be read as proof that the whole cabin is sold. Certain Economy booking classes also have paid advance-seat options. The retrieved ANA page describes advance web assignments until 48 hours before departure and international online check-in from 24 hours until 75 minutes before departure. Keep those two windows separate. After saving, review the assignment on every sector and confirm any displayed charge; do not assume one selection or payment automatically covers a connection.

Important unknowns
- Agency/partner booking eligibility and seat price depend on the reservation.
- Live canonical owner and nearest-page content are UNKNOWN because the sitemap index could not be retrieved.
