For the NS26 longhaul, not much has been added (yet). The only real addition I am seeing so far are 3 extra IST NRT roundtrips, so TK will go 10 weekly to NRT and daily to HND next summer. All other extra frequencies are already operating or have operated during NS25. Interestingly, TK has not (yet) loaded any of the additional China frequencies it is currently operating into PEK, PVG and CAN, so all of those flights are currently slated to end come late March.
