> So it is possible (though pretty unlikely) that Boeing failed to follow their protocol, e.g. didn't send out the right notices on a timely bases or something From what I have been reading in other articles (sources available if you wish), most of the comments from folks in the industry have been that Boeing DIDN'T give the normal, proper notice to airlines. The prevailing sentiment is that most everyone was caught relatively unaware that this feature had been shipped on the new airframe. Mind you this is mostly hearsay from mainstream media, so I am taking this with a grain of salt. Oversights tend to get sensationalized.
