When Delta installed iPads at its JFK International Airport gates in 2010, the response was enthusiastic. Now iPads are a big part of their renovations at La Guardia. LGA passengers can order food, have magazines delivered to their seat, shop and browse the Internet from cafes equipped with iPads. Seats by the gates also have iPads, allowing passengers to play games and shop at nearby stores. Renovations at Terminal C and D cost $50 million. Rick Blatstein, CEO of OTG Management which owns and operates the concessions in the terminals, told The New York Times that there is revenue potential in spaces at boarding gates, filled with people who have nothing to do but wait.
