FOR DELAYED LUGGAGE:
Fill out all information about your luggage on the forms provided. present them with your baggage claim ticket (what you were given when you checked your luggage in at departure). Be as detailed as possible. They will track it, get it on the soonest available flight and have it shipped to wherever you are staying, or forward it to your next destination. Get a phone number to call in case you need to follow-up. Make sure to keep note of who you talked to and when.
If you need basic amenities such as toothbrush, toothpaste and razor to be ready for a meeting, ask. Most airlines will provide these for you while you’re waiting for your suitcase.
FOR LOST LUGGAGE:
If the airline actually loses your bags, make sure you get a written claim for damages. This may require a different form than the original “missing luggage” form. This can be done at the airport or by mail.
For international flights, the limit is $9.07 per pound (or $20 per kilogram) for checked baggage, and $400 per person for carry-ons (sometimes this amounts varies by airline). You may need to produce receipts. If you have them, include copies in any documentation you send to the airline. You can purchase “excess valuation” protection if your checked baggage is worth more than these limits.
If all else fails be sure to file a complaint immediately. If you still can’t get satisfaction, or feel the need to report the airline, write or call:
