Why would we look at revenue? I can sell a dollar for 90c and have very high revenue. The CEO's salary is ~2% of profits. Their profit margins were ~5%.

Assuming your numbers are accurate, if they magically were able to pay their CEO $0, their profit margins would be 5.1% instead of 5%.

What's your point exactly? How does this address my point that airlines are extremely price-competitive and will continue to be so?
