It depends on the reason for cancellation:

 - Cancel within 24 hours of booking and your flight is scheduled 7+ days away
•  Purchased an Economy, Premium, or Business bundle

•  Are an Elite member canceling 7+ days before departure

No-Shows
• If you don’t cancel and don’t show up, your ticket and associated fees are forfeited

Refunds are issued to the original form of payment used for the affected reservation.
