that came to the assistance of passengers, just one sign of the influence of the far-reaching impact of global airline alliances and codeshare agreements.

If pilot error were to emerge as a cause of the crash or a contributing factor, another aspect of the carriers' relationships could come into play, because a U.S. law requires that U.S. carriers conduct periodic safety audits of their code-share partners. It is possible that a serious safety issue could prompt a review by one or both of the U.S. partners, United and

US Airways



Both carriers, like Asiana, are members of the Star Alliance, and both also have code-share agreements with Asiana to facilitate travel between Korea and the U.S. Spokespersons for the two carriers declined to say whether any of the passengers on the flight had booked Flight 214 through them or had booked connections on their flights through Asiana. It is reasonable, however, to assume that the latter did occur.

The practice of United, as a Star alliance member, is to assist an international carrier that has an accident in the U.S. In this case, United hosted the flight's passengers and in some cases their families in its club, providing food and beverage as well as telephone and Internet access. Additionally, United, like other carriers, waived change fees for SFO passengers because of the hundreds of delays and cancellations that resulted from an airport closure and subsequently from the shutdown of a runway.

At a news conference Monday, National Transportation Safety Board chairwoman Deborah Hersman said that United and Asiana employees are providing support to 120 crash survivors and family members. The NTSB "requires domestic and foreign carriers to have plans in place to meet the needs of victims and family members," she said. Asiana's responsibilities include arranging travel and lodging for survivors and their families.

As for the potential safety issue, in 2000 the U.S. Transportation Department established a code-share safety program requiring U.S. carriers to conduct safety audits of their foreign partners. The program's establishment followed

after a series of accidents including a 1997 crash in Guam that killed 227 people.

"People got jittery about that," said aviation consultant Bob Mann. "KAL had cultural issues, cockpit resource management issues, that caused junior people to not say anything to a senior person." Historically, similar issues have occurred at U.S. carriers as well. Delta sent a team to help KAL overcome the problem.

"If it turns out there are safety culture issues that arise in the Asiana crash, it would be appropriate to invoke those standards" of the code-share safety program, Mann said, adding: "I would think the partners would want to." Mann consulted for Asiana, regarding non-operational issues, in the early 1990s. He did not observe any safety issues at the airline then.

Nevertheless, "Asiana's accident is going to damage the image of not just Asiana, but all Korean airlines," Um Kyung A, an analyst at Shinyoung Securities Co. in Seoul, told

Bloomberg News

on Monday. "It only takes one incident to undermine years of work Korean airlines have made to get a solid, accident-free record. This will prompt the government to call for stricter safety measures."

Joshua Shank, CEO of the Eno Center for Transpiration, said Monday that "If the NTSB finds that the airlines and/or pilots are at fault, it is likely that other airlines will be concerned about association with Asiana and will act independently of FAA regulations."
