US Airways (UNKNOWN:LCC.DL) saw increases in a number of its key figures last month. On a consolidated basis (incorporating the company's Express unit), revenue passenger miles, or RPMs, advanced by 5.2% from March 2012's number to hit 5.8 billion. Available seat miles, or ASMs, also grew, although not as robustly -- the figure increased 3.3% on a year-over-year basis to 6.8 billion. Load factor rose by 1.6 percentage points over that time frame, coming in at 85.6%.

The latter was due to a record high figure of 86.1% for March recorded by US Airways' mainline service.

On a year-to-date basis, compared with the first three months of 2012, RPMs grew 4.3% to 15.5 billion, ASMs were 1.4% higher at 18.8 billion, and the load factor was 2.2 percentage points higher at 82.4%.
