For example, now we served Dilmah Ceylonese Tea in economy class instead of Lipton. While, ex BKI we served Sabah Tea. New menu/meal choices/desserts. Then, the new child meal box set, children give away and etc. For GCC pax, now we have Kosmo and Harian Metro on some selected routes.
As for styrene cup over GP glass, I think it's a good step though. More portion more liquid and weight reduction.
As for casserole dishes over foil, as stated in the circular.. all related to weight reduction and cost saving.
