PG,
If Delta pilots owned all Delta flying, regardless, then any NEW operation would by default be Delta flying for the Delta pilots. Song is an example of this principle in action.
If we define our flying narrowly to what we perform, then NEW flying by definition is NOT OURS. As the Air Canada pilots discovered as they watched 757's fly way at the hands of AC Jazz "RJ pilots."
Consider ....
Delta has a whole handfull of derelict certificates sitting in filing cabinets ....
When do we object? Now, when we can make a difference, or do we let management establish the pattern ... which they can cram down on us when it is something we care about? Delta management has already run charter operations using "non permitted aircraft."
By re-defining "Delta flying" we have to proactively scope what we think the Company might do. I prefer the default position that we own it all.
