You forfeit your ticket, no refund, if you no show. If you cancel, you might get a refund of certain taxes and fees.
Do I have to cancel my flight or can I just not show up?
The airlines do not really care if you show up for your flight or not. You've paid, they have your money whether you fly or not, and if you don't fly, may be able to sell that flight to someone else.

Is it OK to not turn up to a flight?
Airlines explicitly state what happens to no-shows in their contract of carriage, which is a legal document that explains the terms and conditions of the fare. In general, if you are a no-show for your flight, any subsequent flights on the same itinerary will be canceled without a refund.
Should I let airline know if I’m not flying?
Travelers who are concerned they're not going to make their flight should immediately alert the airline. "If someone knows they will be missing the flight prior to departure, it's good policy (and manners) for that passenger to notify the airline," flight attendant Kelly Kincaid told Travel + Leisure.
What happens if you don’t make your flight?
If you missed your flight due to traffic, the airline may label you as a no show and cancel your entire itinerary. This is why it is important to call ahead and see if you can be rebooked on another flight so that you can still fly. Chances are, you will need to pay the rebooking fee.
