Those arguing against the policy are doing so because they are looking at it from an, operational perspective.
Incorrect.
There operational aspects have been covered. The post quoted above clearly demostrates that JJ has a problem with tech crew. JJ didn;t mentioned operational aspects. JJ mentioned pilots getting something from CC. It was pure spite.
The fact is this is not a significant operational matter. It is safe. There are the number of seats required for people to sit in.
I have talked to many many many CC over the last few days about this. Luckiliy they think JJ is a sad sack who needs to get a life. The vast majority thinks this is a good thing.
