Lufthansa operates to Iran and Iraq and about 20 American cities, including Washington, DC. The German group serves Tehran from Frankfurt, Vienna and Munich, and also flies to Isfahan from Vienna. In Iraq, it offers flights to Erbil in the Kurdish controlled north from Vienna and Frankfurt.
The U.S. government said earlier that it's taking steps to restore order to the air-transport industry following a weekend of chaos sparked by the travel ban. Permanent U.S. residents from nations covered by the Trump order should no longer be detained at American airports, and no one covered by the ban should be getting on planes overseas, the Department of Homeland Security said.
The agency's statements late Sunday sought to end confusion in which travelers, gate crews and immigration officers were left to contend with conflicting edicts. On one side was the presidential order halting travel; on the other, three U.S. court orders blocking parts of the ban.
At New York's John F. Kennedy Airport, protesters on Saturday chanted "Let them in!" and "No hate! No fear! Immigrants are welcome here!" Thousands more gathered from Atlanta to Detroit on Sunday to oppose the restrictions, while at Los Angeles International Airport demonstrators packed into the terminal for foreign flights and snarled traffic outside.
In the hours after the Trump order, many foreign airports imposed blanket bans on U.S. travel for citizens from the seven countries. Students, refugees and dual citizens were stuck overseas, and businesses warned affected employees not to risk leaving the U.S.
In the Gulf, Qatar Airways, Etihad and Dubai-based Emirates are advising passengers from the seven nations that they can fly to the U.S. if they hold green cards or NATO visas, or are diplomatic officials or UN representatives. Etihad also said people of dual nationality may travel if they hold a passport from a country not affected by the ban and have a visa. That's a contrast from the weekend's turmoil.
"There are people who boarded flights to the U.S. and were sent back,'' said a woman who works on the ground staff at Dubai airport. "They left before the decision was made. Then they yelled at us after a 16-hour flight each way.''
