Using Airplane Mode you can disable the phones ability to receive or make calls, texts or email whilest leaving the phone on so that you can look at the screens crappy walpaper and get hassled by the air stewardess for not turning your phone off. The added advantage of this mode is that, when you arrive at JFK, your battery is flat. "Hello Moto" it declares in a cheesy voice, yes hello again. Glad you could make it.
