The U.S. Department of Transportation's website states you can be refunded for your ticket's total cost if there is a cancellation or "significant delay" and you choose not to travel.

"A consumer is entitled to a refund if the airline canceled a flight, regardless of the reason, and the consumer chooses not to travel," the DOT states on its refund website. "A consumer is entitled to a refund if the airline made a significant schedule change and/or significantly delays a flight and the consumer chooses not to travel."

The DOT's website does not define what constitutes a “significant delay.”

"DOT has not specifically defined what constitutes a “significant delay.” Whether you are entitled to a refund depends on many factors – including the length of the delay, the length of the flight, and your particular circumstances. DOT determines whether you are entitled to a refund following a significant delay on a case-by-case basis," the DOT adds.
