Now with my DOne4 planning in earnest, I wish to know which of either cathay or Japan airlines would be better as follows

I could either fly hkg-del-nrt-dps-nrt-gru
hkg-del-hkg-dps-nrt-gru

first option has 3 of my asian segments on Jl
second option has 3 of my asian segment on Cathay

would anyone care to enlighten me on which way to go it is essentially the same although status credits wise it is about 20 more for flying JAL as del-nrt is slightly longer and thus falls into a different band. Really it is about which airport would be better to spend time in and which airline would be better inflight etc

also i apoligies if this should have been posted in the JL or cathay forum although since it encompasses both I would expect that it should be fine in the oneworld forum as it is directly related to a oneworld fare
