Yes, you can cancel a reservation made through the Hopper app, but the refundability depends entirely on the specific terms of the ticket you purchased and whether you opted for Hopper's specialized protection plans. In 2026, most standard "Basic Economy" or non-refundable tickets purchased through the app follow the airline's strict "no-refund" policy. However, Hopper is famous for its "Cancel for Any Reason" (CFAR) and "Change for Any Reason" add-ons, which you can buy at the time of booking. If you have these protections, you can cancel your flight up to a few hours before departure directly in the app and receive a significant portion (usually 80-100%) of your money back in cash or Hopper credit, regardless of the airline's rules. If you did not purchase a protection plan, you must navigate the cancellation through the "Support" tab in the app; Hopper will then coordinate with the travel provider (airline, hotel, or car rental) to determine if any credit or refund is possible. To avoid frustration, always check the "Cancellation Policy" displayed on the final checkout screen before you swipe to pay, as Hopper’s automated systems are designed to process these requests much faster than traditional travel agencies.
