Cost saving.... not health safety?
What is the rationale for such cuts in AC J class catering service (wine, drinks, food)? CX and other airlines offer almost full pre-Covid service in these areas. Salads and entre are kept covered allowing the passenger to remove themselves. I can go to a full service sit down restaurant in Canada. If anything, the air circulation and filtering in the J cabin is far superior to a restaurant.
I understand removing blankets and pillows (but even those would be replaced between flights). The cut in food and beverage service seems to be cost-motivated, hiding under the guise of non-existent Covid restrictions.
