Having flown mostly TK on European flights it has been a while since I had a LX flight. Having hasitated to start a new thread about J Catering, the constant talk of cost cuttings made me fear that I might go hungry on my up coming IST-ZRH-BCN trip and urged me to pop this question

How is the quantity of J meals on European LX flights. Would I need a visit to a airport restaurant in IST before boarding? Thanks in advance.
