For September, American Airlines parent company AMR (UNKNOWN: AAMRQ.DL ) saw modest increases in its key metrics. The company has released its figures for the month and, for the most part, they're slightly higher on a year-over-year basis. Revenue passenger miles crept up by 1.3% over September 2012's number to hit 10.9 billion. Available seat miles inched up a little more, growing by 1.9% across that period to 13.5 billion.
The total number of boarded passengers also advanced, increasing 1.4% on a year-over-year basis to just more than 8.4 million. However, AMR's load factor (i.e., the average "occupancy" of its planes) was 80.7% last month, a drop from the 81.1% of September 2012.
