Jan 4 (Reuters) - Delta Air Lines Inc said on Wednesday it expected a smaller decline in fourth-quarter passenger unit revenue, a closely watched revenue measure, than it had previously forecast.
The No. 2 U.S. airline said it expects passenger unit revenue, which compares sales to flight capacity, to be down 2.5-3.0 percent for the current quarter, compared with its previous forecast of a decline of 3 percent.
