In Illinois, from what I gather from looking at the plumbing code, and "air gap" is not required for the drainage hose of a dishwasher. However, is it recommended to use one, as opposed to making the "high loop" in the drainage hose under the sink cabinet? Is the high loop usually enough?

The air gap is to prevent any back-syphoning of waste material in the garbage disposal or drain pipe from entering your dishwasher.
Even if it's not required, it's a good idea to have one. The cost is the price of an extra couple feet of hose and the air gap.
Sometimes pieces of food begin to clog the drainage hose and I would recommend the air gap even if it's not required by code.

Air gaps were over-hyped when they first came on the plumbing scene. After a couple years of being code, many areas changed their minds. Too many clogging problems with the air-gaps. I have installed DW's for over 20 years and always used the loop system. Not looping the drain hose will always cause a problem.

Many municipalities require and actual air gap device. If yours does not it is best to do the high loop. Otherwise, you run the risk of water being drained from your sink running down into your dishwasher.

Some of the new dishwashers have a air gap intigrated. So check your manual. If in doubt put one in.
