If you’re headed to the airport in the D.C. area Monday evening, check with your airline first. BWI urged travelers to "rebook now!"
A temporary ground stop is in place for Dulles, Reagan, and BWI airports because of construction fumes at an FAA air traffic control facility in Leesburg, Va.
This affects all air traffic, Dulles reported. Any flights scheduled to take off are stuck on the ground. Many flights in the air trying to land will have to circle the airport before getting the all clear to land.

According to an FAA statement, fumes from construction work made their way into the control room, which handles high-altitude flights over the D.C. area. Workers had to stop accepting new flights and handed off airborne flights to other air traffic control facilities.
"We are actively working to ventilate the facility. Controllers are handling a reduced number of flights safely," the FAA stated.
There was roofing work being done on the building and some of the fumes from the adhesives got into the HVAC system, Loudoun County Fire Department spokeswoman Laura Rhinehart said.
Medics evaluated all 51 people who were inside the building. One woman was taken to a medical facility as a precaution after being exposed to the fumes.
