William Blair analyst Louie DiPalma noted that Delta's (DAL) CEO said at the SKIFT conference on September 18 that free Wi-Fi will be available soon, but neither his company nor partner Gogo (GOGO) had previously provided a timeline. However, on Twitter today Delta said it anticipates the launch "will be sometime this year," which DiPalma said is "much sooner than what we believe buy-side investors are expecting." He sees the potential for the launch to prompt consensus estimates for Gogo's FY20 to be raised and project that Gogo shares will appreciate to a range of $10 to $15 in 2021, added DiPalma, who keeps an Outperform rating on the stock.
