If you are in IAD and want a place to pray and meditate before your flight, the airport has a chapel. You can find an inter chapel across gate A32 in the A gates. For those in BWI, there is a meditation room located near the D/E security checkpoint on the upper level. DCA also has an interfaith chapel across from the Delta Airlines gates, at the south end of concourse B. On arrival at ATL, you can find chapels at the pre-security area in level 3, international concourse E, and international concourse F. These chapels are always open.
