US-based United Airlines has announced the opening of its redesigned Transportation Security Administration (TSA) Precheck security checkpoint and three automated screening lanes at Chicago O'Hare International Airport.

With the new lanes in place, up to five customers will be able to fill individual luggage bins simultaneously, speeding up the screening process.

The lanes also use a parallel conveyor system that will automatically return empty bins to the front of the queue.

United Airlines executive vice-president and chief operations officer Greg Hart said: "As the first and only US-based airline to launch automated screening lanes in multiple airports, United continues its commitment to using the latest technology to meet the changing needs of our customers and improve the airport experience.”

"We are very appreciative of the ongoing collaboration between TSA and our industry partners, such as United."

Last month, automated screening lanes were launched at the airline’s hub in Los Angeles.

New lanes are also expected to open at Newark Liberty International Airport, United’s Trans-Atlantic gateway.

Once United completes the installation in collaboration with the TSA, the newly centralised security checkpoint at Newark Liberty will feature 17 automated lanes.

TSA administrator Peter Neffenger said: "We are very appreciative of the ongoing collaboration between TSA and our industry partners, such as United.

"Working together in our efforts to deploy effective, state-of-the-art technologies, such as these automated lanes in Terminal 1 at O'Hare, furthers TSA's ability to fulfil its security mission while also enhancing the travel experience."

United is also building and redesigning checkpoints at several hubs throughout the airline's network.

The airlines will install audio and visual enhancements and consolidate four checkpoints into one centralised checkpoint at Newark Liberty.

Security checkpoints at Chicago O'Hare will be redesigned, while a new customer check-in area and checkpoint will be constructed at Los Angeles International Airport.
