Chicago to Honolulu Fares Using Expedia Comparison

I used Expedia's Comparison Engine to track Hawaii flight prices from Chicago, IL to Honolulu, both from Ohare (ord) and Midway (mdw). I found general average lowest prices of:

These prices are from O'Hare Airport (ORD)

This week: $800

Mar 5-11: $600

March 12-18: $580

March 19-25: $650

March 26-April 1st: $600

April 2-8: $680

Apr 9-15: $650

April 16-22: $680

April 23-29: $600

Month of May: $600

Month of June: $700

Month of July: $750

Month of August: $700

Month of September: $650

Month of October: $650

Month of November: $780

Month of December: $800

Now from Midway Airport (MDW), Chicago Illinois

March: $690 - prices are all over the place, and seem to climb higher on the weedends than O'hare prices

April: $700

May: $650

June: $800

... There does not seem to be a significant price difference between the two airports.

My searches were based on one week, wednesday to wednesday travel. Anything leaving or coming back Friday through Sunday or around holidays will almost always be more, sometimes significantly more.
