China Southern Airlines in summer 2020 season plans to operational aircraft changes on Wuhan – New York JFK route, scheduled 3 times weekly. The airline plans to operate 309-seater Boeing 777-300ER aircraft from 29MAR20, instead of 282-seater 787-9 Dreamliner.
This adjustment was filed in the past week, however Airlineroute is unable to detect whether this was filed prior or after the Wuhan shut down.
