Global Premier Upgrades.
Global Premier Upgrades on ANA-operated flights are valid for one-segment, one-cabin upgrades on any multi-cabin international flight operated by ANA and marketed by ANA or United. Upgrades are subject to availability and valid for paid, published fares only. The following ANA fare classes are eligible for Global Premier Upgrades: C, D, J, Y, B and E.
