Not exactly sure but I know lunch ends at 1:30, and free alcohol is from 4:30-7pm departures on weekdays, and that all flights until October have great service. Times are of departure.
I was talking to an NZ manager yesterday about what the definition of a snack was. He was not sure, but if meals are gone and it is replaced with their morning and afternoon snack, then I will not be too unhappy as you get a really nice facacia (spell?) sandwich.
