Customers on around 55 domestic flight segments a day will have an opportunity to surf the internet free of charge, starting May 13. The two-week pilot across all cabins on select short-, medium- and long-haul routes is Delta's first step toward realizing its vision of offering free in-flight Wi-Fi as part its leading suite of complimentary onboard entertainment options.

"Customers are accustomed to having access to free Wi-Fi during nearly every other aspect of their journey, and Delta believes it should be free when flying, too," said Ekrem Dimbiloglu, Director of Onboard Product. "Testing will be key to getting this highly complex program right – this takes a lot more creativity, investment and planning to bring to life than a simple flip of a switch."
