Introducing Airport Info- Alerts: You'll be notified of important information, like airport weather delays*, parking lot capacity and AirTrain service changes. Free alerts are sent directly to your cellular phone, PDA, pager or e-mail account. (*Check with your airline directly for specific flight delays.)
Wi-Fi service is available at John F. Kennedy International, Newark Liberty International and LaGuardia -- most public places are "hot spots" offering high-speed connectivity. You can jump online near ticketing, your boarding gate, workstations and in the food courts.
