What do I do if my bag does not arrive at my destination?

If your baggage is missing, it is extremely important that you file a report at the Gulf Air baggage services counter at your arrival airport. While the staff makes efforts to investigate the whereabouts of your baggage, you will then be given a baggage tracking number, which you can use to track the status of your baggage claim. In most cases, delayed baggage is located within 24 hours and, once found, is usually arranged for delivery to your ultimate destination (i.e., home or hotel).
