You can check fares, fees and flight schedules for just about any airline in the world with a few keystrokes or a single phone call. But checking safety of an international airline is much more complicated.
European and U.S. regulators evaluate aviation safety, and the airline industry itself has a worldwide safety-audit program, but it's difficult for travelers to check airline safety when buying tickets.
That's unfortunate. It's been a bad year for aviation fatalities, with more than 700 people killed in 16 crashes around the world so far in 2009. Many involved little-known airlines -- some already on watch lists for safety concerns.
"There's no perfect solution at the moment, but it's undoubtedly getting better," said Geoff Want, adviser on airline safety at Rio Tinto Group, a global mining company that has its own list of carriers approved for employee travel.
Government regulators in Europe and the United States take different approaches.
The European Union evaluates airlines and their planes and publishes a "blacklist" of unacceptable carriers, updated two weeks ago. The blacklist is on the Internet at ec.europa.eu/transport/air-ban/doc/list_en.pdf.
Be prepared, it's long and complex: 233 airlines are completely banned, and eight are allowed to operate under restrictions. Though its focus started as an airline-by-airline evaluation, the EU has moved toward building the list on evaluations of countries -- all airlines from 15 countries have a blanket ban from the EU.
The U.S.' Federal Aviation Administration evaluates countries, not carriers. Inspectors decide if a country's aviation infrastructure is up to snuff, counting the number of inspectors watching over airlines, assessing air-traffic-control procedures and evaluating funding and legal authority of regulators. The FAA evaluation is based largely on standards set by the International Civil Aviation Organization, a United Nations-chartered group.
