Whilst J is a great product, economy class is actually pretty good as well and I put this down to good catering and attentive staff (well, as attentive as one can expect for overnight flights). I have taken 16 JX economy flights in the last 2 months, all in economy. I am 6ft 3" and even I find the seating ok. I is amazing that after a 11-14 hour TPAC flight, the toilets are always immaculate and breakfast is served with a smile. JX is now my economy class TPAC flight of choice.
