United and Delta both pay separate pay rates for different gauges of the same type. The two biggest airlines in the US. No mandate huh?
So you are wrong in your spewing.
Later....
Delta actually pays LESS on the MD88-MD90 than they do on the A319,A320 and 737-700, even thought the MD88-90 have MORE seats.
Maybe you are confused by the word mandate. As I have said before (which is why you didn't use the quote feature, because you want to argue what you THINK I said, and not what I ACTUALLY said), some airlines pay more for a common stretched type, some/most do not. There are more examples of common pay then there are more pay.
Even if you were correct, which you are not, the question still remains of HOW to allocate that additional pay moneys, and an override for a small group of 321 pilots, is not the best way, especially since we are ALL so far behind in most/all compensation areas.
It is a matter of priorities and allocation, and you are on the wrong side of both.
