"We are not standing on the sidelines as fanatics hatch new plots", Homeland Security Secretary John Kelly said in Washington.
An aviation source explained to CNN that some of the measures could include an increased use of K9 dogs, interviews of passengers before boarding and explosive trace detection equipment.
According to airline sources, passengers' in-flight experience should not be affected by these changes.
Airline officials told Reuters they are concerned about adding new enhanced security measures to all airports worldwide that have direct flights to the United States rather than focus them on airports where threats are highest.
The U.S. electronics ban that's been in effect since March targeted 10 airports in Egypt, Jordan, Kuwait, Qatar, Morocco, Saudi Arabia, Turkey and the United Arab Emirates. "Those who choose not to cooperate or are slow to adopt these measures could be subject to other restrictions, including a ban on electronic devices on aircraft or even a suspension of their flights into the United States".
This story is developing.
Earlier this month, Kelly told CNN that the 10 airports that were first hit with the laptop ban would be given an opportunity to get off the list if they took certain measures.
The new order will cover about 2,000 flights a day from 280 airports in 105 countries, a move that could make global flying even more onerous just as the busy summer travel season starts.
Now, however, the US government will seek to apply new rules to flights regardless of where they originate.
The DHS is implementing new enhanced security measures for all commercial flights coming in to the United States.
There are no plans for an expansion of the in-flight laptop ban, which was put in place in March. Laptops and other devices larger than cell phones will be allowed back on those flights if airlines follow the new rules.
The government had considered expanding the laptop ban to include some European airports, though in recent public comments Kelly had suggested the government was looking at alternatives. Find out what these 100 members of Congress have to say about it. Suspicious bags can be pulled aside and opened by screeners. The technology could potentially let passengers leave liquids in their carry-on bags, speeding wait times.
The test comes as US officials scramble to deal with potential new threats, including reports that terrorists are developing bombs that can be disguised as laptop batteries.
One big issue facing policymakers was the potential safety implications related to past problems with laptop batteries and storing large numbers of laptops in the cargo hold.
