SWA claim they thought they had AOA Disagree
"Southwest Airlines says Boeing didn't disclose it had deactivated safety alert on 737 Max jets"
So says Bloomberg, quoting the WSJ. I shan't copy-paste the article here, and I don't believe I can post a link, but the essence is that SWA are stating that their manuals showed the AOA Disagree alert as being a standard feature, not optional, and that they did not know it was optional until after the Lion Air incident. They're also saying that the AOA Disagree alert was standard fit on the NG.
