I saw this fare in Expertflyer when running a fare check on round the world fares NYC//NYC for 8/22 to 9/6. This joint 'roundtrip' MU(China Eastern)//CI (China Airlines) fare displays as a business class fare at $2550.

There's routing in the rule and it frankly looks more like a Circle China fare with a NYC origination.

Has anyone used this fare - is it legit? Here is the fare rule:
