You can cancel your Chicago plans at any time, but the cancellation duration is very important i.e. if you can cancel your Chicago journey before two days of travel, you will be refunded some amount. If you just cancel your Chicago trip just before an hour of travel or about your commencement of travel, it's very difficult to claim the refund amount from the travel insurance company providing your travel insurance.

Since the companies have their own policies and terms, it is better to read all the terms about cancellation and refunding of your cancelled travel insurance will be better. Many Chicago companies have a "Cancel For Any Reason Travel insurance Plans", with which you can cancel your journey at any time.
