A steady decline in airline traffic at Orlando International Airport (OIA) in the US has forced officials to decrease the airport’s $1bn construction plan by a third.

The airport has indefinitely delayed more than $300m worth construction projects due to a decline in passenger traffic which has led to 10% less fees collection by Greater Orlando Aviation Authority since last summer.

Ricondo & Associates of Miami, the airport’s aviation economic consultant projected that the number of passengers flying through Orlando International Airport will not return to 2007-08 levels before 2015.

Despite the slowdown, the airport will spend approximately $667m for terminal, parking, roadway and airfield projects in the next five years.

In addition, more than $200m is being spent on the renovation of two satellite.

The airport will also invest in new technology for baggage inspections, runway and taxiway improvements, and new rental-car facilities.
