We have tickets DEL-PEK arriving PEK 12:25 and departing on PEK-EWR 3:45PM on United. Both are Star Alliance arriving and departing T3 at Beijing. The tickets were purchased separately. Will we be able to check our luggage in DEL through to EWR? or Will we have to claim it in PEK and then have to recheck in PEK and process through imigration in PEK. Also is there sufficient time? We have multi-entry Chinese Visas.
