Is Shanghai Airlines Part of SkyTeam Alliance? Flight Experience from Tokyo to Shanghai (Feb 2024)

This time, I took a flight with Shanghai Airlines (FM) from Haneda, an airport located in Tokyo, to Shanghai Pudong Airport (PVG). There wasn’t much information available about using SkyTeam’s SkyPriority, so I thought I’d share my experience. The flight I took was FM896, operated by Shanghai Airlines but ticketed through China Eastern Airlines (MU8634). It seems this flight also has a codeshare with JAL (JL8261).
