Airlines around the globe are scrambling to change their policies for all U.S.-bound flights this week after the Trump administration announced a new vetting process for foreign passengers entering the country, set to take effect Thursday.

The White House guidelines date back to July when a deadline of 120 days was given for airlines to comply. This Thursday marks that deadline.

Airlines contacted by Reuters said the new measures, which could include short security interviews with passengers, would be in place by Thursday.

They will affect 325,000 airline passengers on about 2,000 commercial flights arriving daily in the United States, on 180 airlines from 280 airports in 105 countries, and industry trade group Airlines for America has said the changes might cause disruptions.

European and U.S. officials told Reuters at the time that airlines had 120 days to comply with the measures, including increased passenger screening. The 120-day deadline is Thursday. Airlines had until late July to expand explosive trace detection testing.

Lufthansa Group said on Tuesday the measures would be in place by Thursday and travelers could face short interviews at check-in or at the gate. Economy passengers on Lufthansa’s Swiss airline have been asked to check in at least 90 minutes before departure.

Cathay Pacific Airways Ltd said it would suspend in-town check-in and self bag-drop services for passengers booked on direct flights to the United States. The airline said passengers would also have short security interviews and it has advised travelers to arrive three hours before departure.
