Again, the classic dodge...Who do you work for?
How about answering the question? How do you justify comparing apples to watermelons? And the answer, "we just want more money" doesn't qualify as an answer.
How about comparing concrete data and statistics? Profit/loss statements. RPMs. Every metric by which aviation operations are compared.
Of course, your next "answer" is going to be "You must be a joy to fly with." The final refuge of someone who has no logical answer to the question at hand. Don't get me wrong, I hope you get as much money as you can. I just think DAL +2% is unreasonable.
