Travelers might finally be getting a break from the ever-frustrating airport security rules. Thanks to the introduction of new carry-on baggage scanners called CT (Computed Tomography), travelers won’t have to take electronics or liquids out of their bags. The TSA announced the rollout of this new technology, which would ultimately cut down on long security lines and make the airport experience much smoother.

The new machines can create 3D images of a bag’s contents and automatically detect and scan items you are currently required to remove. This includes electronic devices like laptops, and even liquids. According to Bloomberg Government, 300 of these new machines have been ordered by the TSA so far, and they will begin to appear in airports this summer. Eventually, the goal is to replace all current X-ray machines with these new CT scanners. The TSA has been testing these machines since 2017, and once airport employees become comfortable operating the new equipment, shorter security lines are expected.

The list of airports that will receive the new CT machines has not yet been released, though they are currently being used at the following airports:

  • Hartsfield-Jackson Atlanta International Airport (ATL)
  • Baltimore-Washington International Airport (BWI)
  • Chicago O’Hare International Airport (ORD)
  • Cincinnati/Northern Kentucky International Airport (CVG)
  • Detroit Metropolitan Wayne County Airport (DTW)
  • Houston Hobby Airport (HOU)
  • Indianapolis International Airport (IND)
  • John F. Kennedy International Airport (JFK)
  • Logan International Airport (BOS)
  • Los Angeles International Airport (LAX)
  • Oakland International Airport (OAK)
  • Phoenix Sky Harbor International Airport (PHX)
  • St. Louis Lambert International Airport (STL)
  • Washington-Dulles International Airport (IAD)
