Denver International Airport (DIA) in the US has reportedly secured a $317m concourse contract from Denver City Council.
The new approval will see the creation of additional concourse projects, which will change the boarding for all Frontier Airlines passengers.
In 2017, the airport awarded contracts worth $1.5bn to various construction companies for the concourse expansion for the addition of 39 new gates.
With this new approval, the contract’s value is said to have increased to $2.4bn.
Frontier Airlines is said to be the third-largest carrier at DIA, which currently uses nine gates with runways in Concourse A.
By 2024, the airline company plans to shift all its operations to the expanded ground terminal featuring 14 gates.
Once shifted, Frontier Airlines passengers will be able to board and exit the aircraft from the runway through ramps and stairs.
Frontier Airlines has already signed a lease agreement to operate at the airport until 2034 and expects the new configuration to result in quick loading and unloading.
However, it raised concerns that the new configuration would expose its passengers to extreme weather conditions.
Expansion of the Frontier ground loading facility could see a $183m investment, of which some costs will be borne by DIA.
The contract scope also includes apron repairs at some old gates, as well as new de-icing pads.
Last September, DIA upgraded its Lost and Found services to help passengers locate their lost belongings left at the airport.
As part of the upgrade, DIA implemented the Lost and Found Software system provided by Hallmark Aviation Services.
