Another question. Will they get a meal on the Newark to Vancouver portion of the flight, and then a meal on the Vancouver/Auckland flight? Just looking at the website and it says the following

When you travel on a direct International flight that includes a stop in a Canadian city, you will be offered a complimentary snack and a complimentary meal item on the domestic portion of your flight. For example, if you're travelling from Toronto to Hong Kong with a stop in Vancouver, your complimentary snack and meal will be offered to you on the Toronto-Vancouver portion of your itinerary.

Not sure if this will apply to them or not as they actually change planes in Vancouver.
