It may simply be that there aren't enough suitable SFO's for the forthcoming command course's, I know of 2 who have been taken off Decembers course for different reasons.
I flew with a SFO last week and asked when his course was, he said there was a new process whereby he could defer his command course until a vacancy existed at one of his 3 chosen bases. What a great idea that is. saves him having to turn down a course and saves easy from having to replace him at the last moment, or not as the case may be.
Encouraging to see easy are evolving the whole process and how great that I get to fly with this chap a while longer!
