While people-watching, reading and nervously quadruple-checking your boarding pass are perfectly valid ways to pass the time before your flight boards, they pale in comparison to squeezing in a few online rounds of Mario Kart 7. Thanks to a deal between Nintendo and Boingo, 42 airports now have free 3DS WiFi hotspots.

You can check Nintendo’s map for the hotspots nearest you. The feature makes the 3DS a more viable travel companion, but if Nintendo really wanted to make the device more attractive to frequent fliers, they could have given it a battery that lasted longer than three hours.
