Eastern Airlines and Macau Airlines have achieved code-sharing flights on the Shanghai-Macau route.

According to reports, the "mutual endorsement service" launched by both parties this time refers to passengers who have purchased "Shanghai-Macau/Macau-Shanghai" direct flight tickets operated by Donghang Airlines or Macau Airlines. When adjustments are needed in the itinerary, passengers can apply through the original ticketing channel to have their flight transferred to another airline's flight operated by another carrier.
