American Airlines crew was based in Charlotte
American Airlines CEO Robert Isom remains in Washington, D.C., on Thursday to support the families and help authorities.
The flight, number 5342, had 60 passengers on board and four Charlotte-based crew members, Isom said in a letter to American team members.
"Out of respect for the families, we are not sharing the names of the two pilots and two flight attendants at this time, but our thoughts and prayers go out to their loved ones," Isom said.
