Southwest Airlines Co. (LUV) announced today that it recorded a 2.1% decline in passenger traffic for June.

The airline flew 6.7 billion revenue passenger miles (RPMs) last month, compared to 6.9 billion RPMs in the year-ago period.

Available seat miles (ASMs), which indicate capacity, decreased 3.8% to 8.5 billion.

The low-cost carrier also launched one of the biggest fare sales in the company’s history, in which one-way tickets priced between $30 and $90 are on offer to customers for a period of 2 days.

This move by Southwest comes after major airlines raised fares last month in an effort to improve sales.

Meanwhile, 8 of 13 covering analysts lowered expectations on the company’s full-year earnings over the past month, sending the consensus down by 10 cents to 26 cents per share.

LUV, a Zacks #3 Rank (“Hold”) stock, has slipped more than 2% so far today on volume of approximately 3.4 million, which is well below the average daily volume of about 7.5 million.
