USAir Securities Fall After Union Talks Fail: The airline’s stock and bond prices dipped in a sign that investors are growing more skeptical about its future after pilots broke off talks aimed at saving the company millions of dollars annually. The pilots ended the talks after the carrier said it plans to stop flying its biggest airplanes, which means pilots who fly big jets will have to take lower-paying assignments on smaller aircraft. USAir is seeking to cut its expenses by $1 billion a year. The pilots’ share of the cuts amounts to $150 million, and the union and the company have disagreed over what the pilots should get in return for the concessions. USAir’s stock lost 37.5 cents to close at $4.375. Its top bond issue fell $4.75 to $77.125 per $100 in face amount.
