(NBC) - Fewer people are taking to the nation's skies and the experts are starting to blame the economy.
According to data from the Bureau of Transportation Statistics, 68.6 million less people flew on commercial airliners than the previous two years.
The total number of passengers last year fell below the 800 million mark for the first time since 2004. Experts advise the economy combined with increase fees seem to be the biggest factors that are keeping people from flying.
Over the years airlines have tacked on baggage fees and starting charging passengers for meals on board. Some mainline carriers even began charging for sodas on domestic flights.
