More than 60 airlines have been cited for violating the travel ban, including Delta, United, and American.
The airlines have not responded to Al Jazeera’s request for comment.
The airline industry has been hit with a string of travel disruptions since the president signed the travel order on September 27.
A number of airlines have canceled flights, cancelled service, or increased fares since the ban was implemented.
The order, signed by President Donald Trump on September 29, bars nationals of Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen from entering the US.
The executive order was later challenged by airlines, including American, United and United Airlines, and some of its supporters, including President Trump.
The travel ban has been challenged in court, but has been blocked by a federal judge in Washington state.
The court has also granted preliminary injunctions barring enforcement of the ban in New York state.
According to the New York Times, airlines are concerned that the travel restrictions could lead to delays for their flights.
In addition to Delta and United, Delta has suspended all flights to the United States, and United has halted all flights.
Delta suspended flights to Alaska Airlines after the US District Court in the Southern District of New York issued an injunction blocking enforcement of Trump’s travel ban.
United said it had suspended flights from its first two destinations in Europe to Germany, and has also suspended flights in South Africa, the United Arab Emirates, Canada, the Bahamas, and the United Kingdom.
The FAA has issued travel warnings for airlines including American and Delta, which has been criticized for its “tentative and limited” enforcement of restrictions.
Delta has not responded directly to Al Jazeera’s request to comment.
American Airlines has also faced a number of travel issues since the executive order, including a disruption of flights to and from Dubai.
The American airline has not yet responded to our request for comments.
United has suspended flights between Dubai and Miami and between Chicago and Detroit, as well as from its new Atlanta hub.
Delta and American also have suspended flights that were planned to depart from the US and have announced cancellations of scheduled flights.
United confirmed that it has suspended travel from New York, and added that it is working with the FAA to “provide clarity and guidance” on how to comply with the order.
