I took the EDI-DUB Hainan flight at the end of August and there were no more than two or three empty seats in economy. The vast majority of passengers appeared to be just doing the hop to Dublin - certainly the two people next to me were only doing EDI-DUB. I saw a few who appeared to be going onto Beijing - notably the family behind me, but I didn’t notice anyone who seemed to be doing PEK-EDI-DUB though.
