WiFi is becoming common, but doesn’t mean it isn’t complex – Photo: Jason Rabinowitz

A few weeks ago, Gizmodo ran an article claiming to rank and explain every major U.S. carrier’s WiFi system. At Routehappy, a big part of my job is to do exactly that. I need to know exactly what WiFi system is installed on every airline fleet and subfleet in the world, how it performs, what its limitations are, and how it ranks in the overall ecosystem. When I read through this article, I couldn’t help but notice it contained a few errors.

It’s a very complicated ecosystem, but not so complicated that it can’t be figured out. While the article does a great job of explaining how in-flight WiFi works and the technology behind it, I felt it was necessary to clear up which airlines currently offer what systems. Gizmodo’s 1-9 ranking is unchanged.

Below are excerpts from the original Gizmodo article, with my comments added under each.
