Southwest Airlines does not offer bereavement fares for friends and relatives of fallen soldiers, according to the airline's website as of March 2015. A number of other carriers offer bereavement fares for those traveling for a funeral or to be at the bedside of a dying friend or family member.
American Airlines offers special discounted airfares to friends and family members of fallen soldiers, prisoners of war and soldiers listed as dead, injured or missing in action. These and other airlines' "compassion fares" come with certain restrictions and qualifications, so check with the carrier for specific details before purchasing a ticket. Continental, Delta, American Airlines and United Airlines are among the U.S. carriers that offer general bereavement fares.
