On-board internet upgrades
In my experience, Southwest's paid internet service only works about 60% of the time, and when it does, it's painfully slow.
However, I was on a full 737-700 today and the internet was noticeably faster and a speed test showed 10 Mbps. This is still far behind what the legacy carriers have now, but noticeably better than before. I remember the new CEO talked about better internet service being one of his priorities. Have they started upgrading things or was this just a fluke?
