When the courts have to figure compensation for people aboard Asiana Airlines Flight 214, the potential payouts will probably be vastly different for Americans and passengers from other countries, even if they were seated side by side as the jetliner crash-landed.

An international treaty governs compensation to passengers harmed by international air travel — from damaged luggage to crippling injuries and death. The pact is likely to close U.S. courts to many foreigners and force them to pursue their claims in Asia and elsewhere, where lawsuits are rarer, harder to win and offer smaller payouts.

Some passengers have already contacted lawyers.

“If you are a U.S. citizen, there will be no problem getting into U.S. courts. The other people are going to have a fight on their hands,” said Northern California attorney Frank Pitre, who represents two Americans who were aboard the plane.

Federal law bars lawyers from soliciting victims of air disasters for the first 45 days after the crash. Pitre said his clients called him.

Congress enacted that law in 1996 amid public anger over lawyers who solicited clients in the days immediately following the ValuJet Flight 592 crash in the Florida Everglades and the crash of TWA Flight 800 off the New York coast.

National Transportation Safety Board attorney Benjamin Allen reminded attorneys of the rules in a mass email sent Thursday.

“We are closely monitoring the activities of attorneys following this accident, and will immediately notify state bar ethics officials and other appropriate authorities if impermissible activity is suspected,” the message said.

The flight that broke apart recently at the San Francisco airport was carrying 141 Chinese, 77 South Koreans, 64 Americans, three Canadians, three Indians, one Japanese, one Vietnamese and one person from France when it approached the runway too low and too slow. The Boeing 777 hit a seawall before skittering across the tarmac and catching fire.

Three girls from China were killed and 182 people injured, most not seriously.

Two girls, Ye Mengyuan and Wang Linjia, both 16, died right away. It is unclear, however, whether Ye Mengyuan died in the crash or in the chaotic aftermath. Both girls’ parents appeared at a vigil Saturday near the airport, and thanked, through a translator, the more than 100 people in attendance for their support, KGO-TV reported. The other victim killed, 15-year-old Liu Yipeng, died Friday at a hospital where she had been in critical condition since the July 6 crash.

The dozens who were seriously injured — especially the few who were paralyzed — can expect to win multimillion-dollar legal settlements, as long as their claims are filed in U.S. courts, legal experts said.

Northern California attorney Mike Danko, who is consulting with several lawyers from Asia about the disaster, said any passenger who was left a quadriplegic can expect settlements close to $10 million if the case is filed in the United States. Deaths of children, meanwhile, may fetch in the neighborhood of $5 million to $10 million depending on the circumstances in U.S. courts.

In other countries, he explained, the same claims could be worth far less.

In 2001, a South Korean court ordered Korean Air Lines to pay a total of $510,000 to a woman whose daughter, son-in-law and three grandsons were killed in a 1997 crash in the U.S. territory of Guam that killed 228 people.

Broken bones in plane accidents usually mean $1 million settlements in the Unites States and in the low five-figure range overseas, Danko said.

In 2011, the Federal Aviation Administration put the value of a human life at $6 million when it was contemplating the cost-benefit of a new “cockpit resource management” regulation. But again, Danko said, that estimate applies only in U.S. courts. Foreign courts can be expected to pay far smaller settlements.

In all, the South Korean government agency that regulates that country’s insurance industry expects Asiana’s insurers to pay out about $175.5 million total — $131 million to replace the plane and another $44.5 million to passengers and the city of San Francisco for damage to the airport. Suh Chang-suk, an official at Financial Supervisory Service, declined to discuss how the watchdog agency calculated its estimate.
