“It is time that we raise the global baseline of aviation security,” US Homeland Security secretary John Kelly said Wednesday at a news briefing. “We must put in place new measures across the board to keep the travelling public safe and make it harder for terrorists to succeed.”

The new measures, Kelley said, will be both seen and unseen and will be implemented over time. This will include enhanced screenings of all electronic devices, thorough passenger vetting and measures designed to mitigate the potential threat of insider attacks.

The measures will be taken in order to avoid the proposed laptop ban which would have caused major logistical issues as well as safety concerns.

Nearly 200 airlines will have to meet the new heightened security protocols or else they could face repercussions. European and US officials told Reuters that airlines only have three weeks to increase explosive trace detection screening and 120 days to comply with the additional security measures. Kelly added that if airline carriers refuse to follow the new security measures, they could even be banned from operating flights to the US.

“Today is just the starting point,” Kelly said. “We are taking prudent steps to make aircraft more secure, to reduce insider threats, and to identify suspicious passengers.”
