How can I get a refund for my package holiday? While the rules remain the same, many travel agents are ignoring them and you may need to be practical about the best way to get your money back. If you can, consider rebooking for a later date. Travel agents and operators are facing a complete loss of business. The unprecedented pressure to refund so many bookings is pushing some providers to the brink of bankruptcy. So long as you have purchased a package holiday and have an Atol certificate, your money will remain protected – even if the firm does go bust later, you will get your money back. While you’re legally entitled to your money back within 14 days, consider allowing the holiday provider more time if it asks. Abta told us that reason many travel agents can’t repay is because customer money is already with airlines or hotels who, in turn, are refusing to issue refunds. If you can wait until 31 July for your money back, do. Not everybody can or wants to wait. We’ve heard from many people whose financial circumstances have dramatically changed since booking the holiday as a result of the coronavirus crisis. Try explaining this to the holiday provider. If your provider continues to refuse a refund, skip reporting them to Abta. It has said it won’t take enforcement action against its members in regards to complaints about coronavirus-related refunds. Instead, consider using a Section 75 or chargeback through your card provider. Most holiday contracts will clearly indicate what is supposed to happen in the event of a cancellation. If this is a refund and the provider is refusing, you can approach your card provider and demonstrate the contract has been breached.
