Delta Air Lines lost $151.6 million in the January-March quarter, blaming a weak economy and discount fares, the airline said.

The loss amounted to $3.16 a share for the period that is Delta’s third fiscal quarter. Delta reported an $84-million loss, or $2.09 a share, in the same quarter last year.

Delta’s revenue was $2.81 billion for the 1992 quarter and $2.30 billion for the 1991 period.

Thomas J. Roeck Jr., senior vice president for finance and chief financial officer, said the discount fares came at the same time the airline was being forced to pay more in operating costs, particularly in international markets.
