Lost luggage is an airlines issue, not airport. Contact the carrier, usually best to do so on line, have your flight number, ticket / locator number and bag tag # that you were issued. The carrier site will normally have a posted link with Phone #s to contact them and how to submit for the lost luggage. AA has lost my bags several times but has been excellent in getting them to me within 24 hours, this has only happened when traveling away from home and logistics kept moving from town to town with work.
