Earlier today Donald Trump barred visa-holders from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen from entering the US.

The airlines were caught off guard and now Rush to Comply With Surprise Travel Restrictions

Global airlines are struggling to comply with new travel restrictions after being caught flat-footed by President Donald Trump's executive order blocking visitors from seven predominantly Muslim nations.

U.S. carriers didn't get advance notice of the travel ban or briefings from government officials on how it should be implemented, people familiar with the matter said.

The order was causing chaos at airports in the U.S. and abroad as border agents blocked travelers from entering the country and airlines barred visa-holders from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen, as well as people from those countries who are lawful U.S. residents, from getting on planes to the country.
