Oman Air モバイルバッテリー飛行ポリシー。

短い回答

Oman Air is tracked as official from its rendered dangerous-goods policy page: lithium-ion batteries attached to wheelchairs are permitted as checked baggage, spare lithium-ion batteries are permitted in hand baggage with Oman Air approval, one spare battery may not exceed 300 Wh, two spare batteries may not exceed 160 Wh each, and spare batteries must be carried in manufacturer-provided battery containers. The public page currently remains blocked or unreachable to automated citation audit, so the active machine-readable rule still uses the IATA passenger lithium-battery baseline until a stable audit-reachable Oman Air source is available.
