Now that in-flight wi-fi is finally taking off in U.S., at least among early adopters doing the coast-to-coast travels — nevermind the restrictions due to terror threats — the main brand in the space is getting a sky-high round of funding (sorry that’s a bad pun): Aircell, parent of GoGo inflight wireless service, has raised $176 million in a huge new round of funding. No word on who the investors were, but it says was a mix of news and old investors. The money will be used to expand the network, it said. It says it is now installed on 700 commercial aircrafts and has commitments from nine airlines. Glenn Fleishman has a more critical look at the funding and the company’s economics, here.
