The Long Beach Airport will open a new concourse on 12 December, as part of a larger modernisation of the southern California airfield.
The 3,251 square metres (35,000 square feet) facility has the capacity for three million passengers annually, according to the airport authority. It replaces two temporary hold rooms for departing passengers.
Long Beach handled 3.1 million passengers in 2011, according to the airport. Alaska Airlines, Delta Air Lines, JetBlue Airways and US Airways serve the airport, however, the 2011 numbers include discontinued flights by Allegiant Air and Frontier Airlines.
The airport is limited to 41 air carrier slots and 25 commuter carrier slots.
JetBlue, which considers Long Beach a focus city, is the largest carrier at the airport with 85% of the scheduled capacity in December, according to FlightMaps Analytics. Alaska has 6.3%, Delta 4.9% and US Airways 3.8% of the scheduled capacity.
The modernisation project also includes separate improvements to its historic terminal, a new parking garage and aircraft apron improvements.
