To cancel a booking on Trip.com (or most major travel apps like "Trip") in 2026, you must navigate to the "My Trips" or "Account" section of the mobile app. Locate the specific flight, hotel, or train reservation you wish to cancel and tap "Manage My Booking." From there, you will see a "Cancel Booking" or "Refund" button. The app will then display the estimated refund amount and any applicable cancellation fees based on the fare rules of the airline or hotel. For flights, many tickets offer a 24-hour free cancellation window if booked directly, but third-party sites may charge a service fee. Hotel cancellations are often free if done 24–48 hours before check-in, unless you booked a "Non-Refundable" rate. Once submitted, refunds for train and hotel bookings typically take 1–3 working days, while flight refunds can take between 7 to 15 working days to return to your original payment method.
