In the event that your baggage is lost or damaged, you must obtain a Property Irregularity Report from the handling agent at the airport. Failure to obtain this report could result in the decline of any insurance claim..

Should you need to make a claim, this will be required in writing within seven days after your arrival to Sunwing Airlines and will require a copy of the Property Irregularity Report you filed at your vacation destination along with your letter and all supporting receipts.

Make sure you keep a copy of the "lost baggage / irregularity report" - in the worst case scenario, this document is your proof that you informed the airline as soon as possible that your bags were lost.

Loss or damage to baggage while boarding or disembarking must be reported to either the Purser’s Office or the Norwegian Cruise Lines personnel prior to leaving the US Customs area. Passengers must file an Irregularity Report prior to leaving these areas. Norwegian Cruise Lines and Templeton Tours, Inc will not be responsible for any damage or loss which is not duly reported as stated above.

Lost and Found
In case your luggage is lost or damaged, you should immediately proceed to the 'lost and found' counter to fill in a Property Irregularity Report with details about your luggage. If the lost luggage is found, this desk is the place to fetch it.
