In his standup, comedian Louis CK reminisces on his first experience with in-flight Wi-Fi.

“It’s fast, and I’m watching YouTube clips. It’s amazing—I’m on an airplane! And then it breaks down. And they apologize, the Internet’s not working. And the guy next to me goes, ‘This is bull…’ I mean, how quickly does the world owe him something that he knew existed only 10 seconds ago?”

Well, this was only the beginning. Airlines have noticed that when passengers are denied technology to which they feel entitled, they get very frustrated. And it seems that in-flight Wi-Fi has transitioned from being a luxury to an expected standard.

Routehappy, an airline content platform, released a study on the phenomenon’s current state. The report is based on an analysis of all flights worldwide that have at least a chance of Wi-Fi. More than 70 airlines qualified.

Here are the big shocks and awes from the Routehappy report.

Note: Available Seat Miles (ASM) is a standard measure of an airline’s passenger carrying capacity. To calculate it, the number of available seats for sale is multiplied by the number of miles flown.

  • 83 percent of U.S. airlines offer a chance at having Wi-Fi on any given flight.
