3 Charts Showing How Airlines Put a Price on Crash Victims Lives
, , While investigators probe why Germanwings Flight 9525's co-pilot apparently deliberately crashed an airliner in the French Alps last week, the most difficult question falls in the hands of the airline and victims' families How much money is each of the lives lost worth?, Germanwings' parent airline, Lufthansa, will soon offer each family a sum of money to compensate for the deaths of the plane's 150 passengers and crew in hopes the case will be settled. But since prosecutors believe the airline failed to adequately assess co-pilot Andreas Lubitz's mental state  which early investigations suggest may partly explain his motives  some families may be more inclined to seek greater compensation in court. Among the factors that will affect any settlement amount will be the country where cases are litigated. Settlements are partly determined by the victims' wages, age and life expectancy, all of which differ from country to country. Since Germanwings' passengers were nationals of over 15 countries  mostly Germans and Spaniards, with three Americans, Argentines, Brits and Kazakhs  their settlements could vary because of those metrics. See the chart above for a look at how aviation disaster settlements can vary by victims' nationality. The highest average settlements are in the U.S. estimated 4.5 million, several times greater than European averages, according to estimates by James Healy-Pratt, head of the aviation department at Stewarts Law in London. Meanwhile, average settlements in China estimated 500,000, for example, indicate how settlements in Asia tend to be lower than those in Western nations. "The uneven values on the loss of lives of different nationalities in an air disaster has always been a problem to explain to families," says Healy-Pratt. "Especially so given the shared and similar experience of the last minutes of Germanwings.", Though Germanwings may never disclose the value of its compensation offer, the Germanwings victims' families are guaranteed around 170,000 each under an international agreement called the Montreal Convention. Signed in 1999, the Montreal Convention requires an airline to pay that amount as a minimum liability regardless of fault if it is based in one of the 100-some countries that have ratified the treaty, Germany among them. The Convention does not govern minimum compensation for crew members. Though the treaty states an airline is not liable for any amount over the minimum if it can prove it was not negligent, the burden of proving zero fault is "next to impossible to meet," meaning settlements can be unlimited, according to a report by the Danko Law Firm in California. But some countries  such as Russia and Indonesia  have ratified only the older Warsaw Convention, which the Montreal Convention was intended to replace. Signed in 1929, the Warsaw Convention has two fundamental differences from the newer document It sets a far lower minimum liability 8,300, and it states an airline is not liable for any amount over the minimum if it can prove it took all possible steps to avoid the accident. That's much easier to do. As a result, the Warsaw Convention's outdated rules have concerned families so much that when Indonesia-based carrier AirAsia saw Flight 8501 crash last December, the airline's CEO promised he would not "hide behind any convention," the Wall Street Journal reported. In the map below, the countries under the Montreal Convention appear in green, and the countries still under the Warsaw Convention appear in red, , , Meanwhile, some countries have ratified neither treaty and instead rely on national regulations. In Taiwan, for example  the home base of TransAsia, which had two crashes in the last year  there is a minimum liability of about 100,000, according to the Taipei Times. Still, what most airlines have in common, regardless of international treaties, is a policy of immediate compensation. But similar to settlements, these initial payments, too, can vary by country Germanwings, for example, announced last week it would pay 54,000 to victims' families to cover immediate expenses, while TransAsia paid about 38,000 after the caught-on-video crash of Flight 235 in February. "Some unification in this process is needed," a U.S. Senate report wrote in 2003. Compared with other carriers in high-profile disasters, Germanwings has been relatively generous with its initial payment, though these advance payments are often a way for airlines to rehabilitate their public images.
