Fort Worth-based American Airlines (Nasdaq: AAL) is developing technology that could reduce security line wait times by 30 percent, and the technology is coming to DFW Airport early next year.

The DFW Airport Board approved a $3.4 million contract earlier this month for the automated screening lanes project which will be implemented at the five busiest DFW checkpoints. Those are A21, D18, D22, D30 and E18, a spokesperson with the DFW Airport said.

American unveiled two automated security screening lanes at Chicago O'Hare this past weekend. Bags and bins will go through the X-ray machine and either carry on out the other side or be brought to another area to undergo further examination if a potential threat is detected.

Some functions that used to be done manually — like employees returning bins to the front of the line and passengers pushing their bins until they get to the conveyor belt — are now being done by machine.

Some other functions include 25 percent larger bins, radio tags on each bin to improve accountability of items and cameras that snap photos of the outside of bags to match up with X-ray images.

wher the automated security lanes will be in DFW Airport is not known. Each lane costs about $500,000 to build and they take up more room than traditional lanes, an American spokesperson said.

Also, each lane has to be closed for 1-2 weeks during construction, which is why DFW and American are waiting until after the holidays to start construction, an American spokesperson said.

American is also unveiling the new technology in Los Angeles, Miami and New York (JFK).

"In 2016 American Airlines will have spent nearly $30 million on enhancing security and improving checkpoint efficiency at airports across the country," said American Airlines spokesperson Ross Feinstein.
