When faced with wasting precious data allotments, many travelers submit to paying for WiFi on the go. But Sprint customers will find their wallets staying a bit fatter with new, free access to Boingo Wireless hotspots in 35 U.S. airports, starting today.

Sprint and Boingo announced their deal today, without disclosing financial details of the arrangement. Customers will be able to automatically connect to WiFi networks at a slew of airports, the companies said in a press release today, without dinging their data allowances.

“With WiFi being the world’s largest wireless ecosystem, we view it as a highly complementary layer to our network,” said Stephen Bye, Sprint CTO. “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.”

Sprint’s been pushing WiFi connectivity in other ways as well, introducing free calling over WiFi for iPhone customers last month.
