If you’re seeking a refund from Expedia, the process typically depends on the type of booking and the provider’s policies. For refundable bookings, you can cancel directly through your Expedia account or by contacting customer service. Non-refundable bookings may only be refunded in special circumstances, such as extenuating circumstances or through travel insurance. It’s important to review the cancellation policy associated with your reservation before taking any action. If your refund request is approved, it may take several days to process depending on the payment method used. Always keep documentation of your interactions with Expedia for reference.
