澳門航空
Although Air Macau serves as Macau's flag carrier, the Special Administrative Region of Macau flag has never appeared on any of its aircraft, similar to Hong Kong's Cathay Pacific. However, unlike Cathay Pacific, which carried a Union Jack on its aircraft prior to the Hong Kong SAR's 1997 handover, the flag of Portugal never appeared on any Air Macau aircraft prior to the 1999 handover.
