In the middle of last year American started flying its first plane with high speed satellite internet. I lucked into flying the aircraft at the beginning of November, and internet worked though I was surprised it wasn’t faster. I know what Gogo’s 2ku service can do unthrottled and I wasn’t getting anything like those speeds.
I flew American’s inaugural 737 MAX flight at the end of November and the ViaSat satellite internet didn’t work well.
