All food and beverage offered in economy class is available to Main Cabin Select passengers free of charge. According to the flight attendant I asked onboard, you are required to order it on the touch screen. When you do you will notice that your total is zero. Depending on the flight load and duration, you may or may not get served more than once or twice so try to get your order in as soon as the touchscreen allows you after takeoff. They do try their best to get you what you request but it closes long before service in First ends. Another note - I initially expected to be served the same food and beverage as First Class . . . my hopes were obviously shot down. If you have the money, pay for the upgrade to first - well worth the extra attention (not having to order on screen and wait) and comfort.
