Travelers coming into America are now seeing beefed-up security

Airlines are starting to implement additional security measures for international flights to the US, potentially meaning even more hassle for travelers.

The security measures apply to roughly 280 airports in 105 countries and do not affect domestic flights, a spokesperson for the Department of Homeland Security (DHS) told Quartz. The airlines covered by the new regulations announced last month by DHS secretary John Kelly were given time to implement them.

Starting today (July 19), travelers coming in from Mexico, Canada, and Colombia should expect to see the effects. Airlines—a total of 180 will eventually be affected in total—are advising US-bound passengers to arrive earlier to the airport.
