AMR Corp., parent of American Airlines, reported a $20-million profit in the first three months, its first for the January-March period since 1989.

Ft. Worth-based AMR’s profit, which came to 28 cents per share, contrasted with recent losses at other carriers. In the same three months of 1991, the nation’s largest airline lost $195.6 million, or $2.96 per share.

AMR Chairman Robert L. Crandall said bookings have increased 46% since a new, sweeping fare structure was announced last week. AMR’s four-tiered fare structure narrows the gap between the highest and lowest fares by cutting business fares by about 38%.
