Go to routes-->price management. Write down the average price for the 3 classes. Click the tab to reset all routes to default prices, and then write down the new prices. Come back & tell us if there's much difference.
Are you making an overall weekly profit? Can you post a screenie of your income statement?
Looking at your stats, you have good LFs.
Your plane usage is pretty low, looking at the flights from your airport, it seems like you start most planes at 5am or 6am, but only fly a couple of them overnight, when red-eye options are available. It would help if you could keep your planes in the air longer. There are some shorter routes you could be flying, such as PHL, BWI, CLE (this is almost empty, and 800 pax), MEM, PIT, MBJ (100 pax, completely empty), etc.
Looking at your pax graph, you appear to have no business class at all, but do have some first class seats. Is that correct? If so, that is something that could make a lot of difference. Instead of flying 150/0 seat MD90s, change them to 145/4, 135/8 or 130/12, depending on the amount of business demand. Not sure what config your 757-300s are in, but the default 222/15 is decent, and some more business class on that would also be good. You'd do better to fly the 2nd 757 to LAX & somewhere else as well, instead of ANC. Or even LIM + somewhere else, since it's only slightly further, but is a longhaul flight, so has significantly higher ticket prices than a domestic route.
I'd assume you're profitable at the moment, but the profits are only fairly small. Business class seats, planes being in the air longer, and resetting ticket prices to default should all increase that profit margin.
