Do any airlines publish their policy on CRM / Do Not Pair? A question came up recently on Skeptics.se regarding the implementation of "Do Not Pair" lists in Airline operations. I am skeptical of the answer given (irony?) which ascribes the implementation of the Do Not Pair list to the accident on board Northwest Airlink Flight 5719 - an incident which was in part caused by bad CRM.

However, the NTSB report does not suggest any sort of changes to the pairing of Captain/FO's which is what makes me skeptical that anything such as this actually exists within the industry.

Is there any documented evidence that Captains or FO's can in any way affect who they get paired up with? A single example would suffice.
I worked in the industry for 16 years with multiple airlines.

In two of these we had 'do not pair'. Most airlines use computer systems to do their crew planning. In the systems I have used, you can enter against each crew member, others they should not fly with.

The decision as to the use of this laid with Fleet management or Cabin Crew management and was only used in extremist.

In both airlines however, this was not a documented procedure.
Hope this helps.
