What you'll learn in this report:If your flight is canceled or significantly changed and you decide not to travel, you may be entitled to a refund, even on a nonrefundable ticket.

A short delay on your first flight can turn into a much longer one if you miss a connection, so check when your revised itinerary gets you to your final destination.

Hotels, meals and replacement flights aren't guaranteed in every disruption, but asking the airline about its policies before spending money could help.
