The TSA is still considering cutting down on security at more than 150 smaller, regional airports, but there may also be some new additions.
They're not too common, but 3D scanners are being used in some cities, giving agents the ability to see through a cluttered bag. They're at more than dozen airports now.
Now, the TSA says we could start seeing them at even more airports.
Those 3D scanners could also allow you to keep your shoes on and keep liquids in bags.
Another change could be coming on four legs. TSA is thinking about adding more canines to airports, and it could also shorten your wait time in line.
If dogs are brought in to more airports, the passengers getting sniffed would be able to move to a separate security line.
Also, certain airports are currently rolling out automated screening lanes.
These lanes are similar to the usual security lines, but as soon as you put your belongings on the conveyor belt, you can skip ahead of the person in front of you. From there, you go through body screening.
TSA is still putting these in place at some airports.
To put TSA's work in perspective, it is responsible for security at about 440 airports, and its 43,000 employees screen more than 2 million passengers every day. Additionally, they screen 1.3 million checked items and 4.9 million carry-on bags.
