This is the online process information form that must be completed for resolution or compensation in situations where your baggage has arrived after the flight or not arrived at all, or if there are items missing from your baggage.

If you leave the airport without filing a Lost Baggage Report, or if you have already submitted a report and wish to track your baggage, you need to complete an online baggage issues tracking form. To address delayed baggage deliveries, please complete the online baggage issues tracking form within 21 days to seek compensation for any damages and expenses incurred prior to the delivery of your baggage. To report damaged baggage or missing items, please complete the online baggage issues tracking form within seven days.

Along with your passport, boarding pass, and baggage tag, please include various documents such as an item list, photographs, and invoices with the tracking form for each issues application.

Your baggage may be delivered to your address by cargo, or you might need to collect it at the airport, depending on the country's customs regulations. The delivery status of your baggage can be obtained through the contact information given during the application process or by referring to the PIR (Property Irregularity Report).

First five days starting from the non delivery of the baggage you can obtain updates regarding your baggage status by using the station contact number provided in your report. Alternatively, you can monitor the status of your lost baggage by logging in with the reference number (e.g. ISTTK12345) on the baggage issues tracking page through the property irregularity report (PIR). If your lost baggage is located, you will be contacted regarding its delivery.

The Property Irregularity Report number serves as your reference for tracking the process through the baggage tracking form.

• Avoid placing valuable items (such as money, jewelry, credit cards, etc.), essential items (including medicines, keys, business documents, etc.), one-of-a-kind items (like manuscripts, family heirlooms, works of art, etc.), and delicate items (such as electronics, eyeglasses, glassware, musical instruments, etc.) in your checked baggage.
• Avoid traveling with baggage that has been previously damaged, including suitcases, duffle bags, and other containers. Previously damaged baggage and/or the contents of such baggage could sustain further impairment and/or become unusable.
• It is advisable to use a TSA (Transport Security Administration)-approved baggage lock to safeguard your belongings. In this way, TSA agents can open your luggage for security checks without breaking your locks.
• It is advisable to write or leave your name, phone number or email address in your baggage to facilitate contact in the event that your baggage tag becomes damaged.
• If the overhead bins in the cabin are at capacity, your cabin baggage may be placed in the aircraft hold. As such, please organize important, valuable or delicate items (such as money, passport, medicine, computer, etc.) in a way that allows for quick access and removal from your cabin baggage. If you cannot remove these items from your cabin baggage, please notify the cabin crew.
• Once your luggage is packed, it is advisable to take a photo of the bag in its closed and open states. This will be helpful in identifying any damage should a baggage issue arise.

Typically, the Lost and Found offices are located in the airport’s baggage claim area. For instance, Lost and Found offices are located in the baggage claim lounges of both the domestic and international terminals at Istanbul Airport.
