Orlando, Fla.-based AirTran said in a statement that it refunded the passengers' air fare and planned to reimburse them for replacement tickets they bought on US Airways. AirTran also offered to take the passengers back to Washington free of charge.
"We apologize to all of the passengers—to the nine who had to undergo extensive interviews from the authorities and to the 95 who ultimately made the flight," the statement said. "Nobody on Flight 175 reached their destination on time on New Year's Day, and we regret it."
The airline said the incident on the flight was a misunderstanding, but the steps taken were necessary.
A U.S. Muslim advocacy group, meanwhile, filed a complaint Friday with the U.S. Department of Transportation. "It is incumbent on any airline to ensure that members of the traveling public are not singled out or mistreated based on their perceived race, religion or national origin" the Council for American-Islamic Relations said.
One of the Muslim passengers, Atif Irfan, said the family probably would not fly home with AirTran because members had already booked tickets on another airline, but appreciated the apology.
"It's definitely nice to hear," he said.
Irfan said when he boarded the flight Thursday, he mentioned something to his wife and sister-in-law about having to sit in the back. His sister-in-law replied that she believed the back of the airplane was the safest, but Irfan believed it was better to be by the wings.
"She said, 'Yes, I guess it makes sense not to be close to the engine in case something happens,'" Irfan recalled Friday. "It was a very benign conversation."
Shortly after taking their seats, members of the group were approached by federal air marshals and taken off the plane, Irfan said. They stood in the jet bridge connected to the airport and answered questions while other passengers exited and glared at them.
