American Eagle Airlines boosted the number of flights being flown and increased passenger traffic by 18.8 percent in March compared to the same time period a year ago.
The AMR Corp. subsidiary said Tuesday that paying passengers flew 789.6 million miles last month, compared with 664.5 million in March 2010.
American Eagle also increased passenger-carrying capacity by 20.4 percent, to 1.11 billion available seat miles. A seat mile is equal to one seat flown one mile.
With the number of available seats rising faster than traffic, average occupancy fell to 71 percent from 71.9 percent a year ago.
Fort Worth-based American Airlines, also a subsidiary of AMR, flew 10.66 billion revenue passenger miles in March, a 0.8 percent increase compared with March 2010, on a 2.6 percent increase in seating capacity, company officials said.
Traffic was up 13.9 percent last month in the Pacific, up 12.1 percent in Latin America, but was down 8.1 percent in the Atlantic and down 1.7 percent in the United States, compared with March 2010, airline executives said.
For the first three months of the year, American flew 29.16 billion revenue passenger miles, a 1.6 percent increase compared with the first three months of 2010, on a 2.7 percent increase in capacity.
