When you're sitting around at the airport waiting to board your flight, what do you do to pass the time? Play around on your smartphone, right?

Playing games and checking social media can be an awesome distraction, but it can really cut into your smartphone data plan — especially if your fight is delayed for hours on end. Sprint wants to change that.

The carrier on Thursday announced a new partnership with Boingo to offer its customers free Wi-Fi in 35 major airports across the country. Sprint says the deal will make connecting to Wi-Fi at airports as "easy and safe" as cellular. Thanks to the new partnership, Sprint devices within proximity of a Boingo hotspot can automatically connect to the Wi-Fi network, so you won't have to manually search for Wi-Fi and log in.

"With Wi-Fi being the world's largest wireless ecosystem, we view it as a highly complementary layer to our network," Sprint CTO Stephen Bye said in a statement. "By enabling customers to move seamlessly between secure Wi-Fi and cellular, our customers will have a better mobile experience in more locations, all while lowering their cost of data usage."

The auto-authenticating Wi-Fi service is available at no additional charge to all Sprint customers with capable devices. Usage while connected to Wi-Fi will, of course, not count towards your monthly service plan.

"Boingo's relationship with Sprint removes the traditional barriers between Wi-Fi and cellular service," Boingo Wireless CEO David Hagan, said in a statement. "Sprint is a market leader with the integration of Wi-Fi and cellular, which is a very customer centric solution to provide an always-best-connected experience through either network."
