Labor Department Reports Lower Airfares in January

January's U.S. airfares decreased 0.6 percent month over month on a seasonally adjusted basis and 5.1 percent year over year, according to the U.S. Bureau of Labor Statistics' Consumer Price Index. This marks three consecutive month-over-month declines, according to the report. Analysis by Seeking Alpha noted that carriers are competing more in key markets due to increased capacity.
