Airfare at the Minneapolis-St. Paul International Airport (MSP) jumped 23.3 percent between the second quarter of 2009 and the second quarter of this year, according to data released Monday by the U.S. Department of Transportation's Bureau of Transportation Statistics (BTS).

That marks the second-highest increase among the 100 largest airports in the country based on passengers.

The average domestic fare originating from MSP was $393 in the second quarter-up from $319 during the same period last year.

The national average for the 100 largest airports, by contrast, was $341, representing a 13.1 percent increase from the second quarter of 2009. The figures include both round-trip and one-way trips but do not include baggage fees.

The average U.S. fare was down 4.8 percent from the all-time high of $358 in the third quarter of 2008 but up from the post-9/11, second-quarter low of $301 in 2009.

The $393 average airfare in the second quarter of 2010 represents a 0.5 percent increase since the second quarter of 2000; meanwhile, the overall increase in consumer prices has risen 26.4 percent during that period. Since 1995, when BTS first began recording prices of flights, fares have risen 14.8 percent compared to a 42.9 percent inflation rate.

Average fares varied greatly in various cities across the United States. Huntsville, Alabama, had the highest second-quarter fare of $485, and Atlantic City, New Jersey, had the lowest fare of $178.
