The average airfare paid in the US declined 2.7 percent from March to $267.48 in April, the largest decline in more than four years, according to the Department of Labor's Consumer Price Index (CPI). The drop ended three consecutive months of month-over-month increases. April's average airfare represented a 6.9 percent year-over-year fall in the index, which largely measures discounted economy fares and specifically excludes flights for business travel. The index for lodging away from home, however, increased 0.7 percent in April. These numbers were part of a report showing the CPI increasing 0.2 percent overall in April after falling 0.1 percent in March. Most other items also rose in price, but airfares were part of a declining group that included used cars and trucks, new vehicles and recreation.
