During excessive tarmac delays and to the extent practicable, Dulles Airport supports our airline partners in the deplanement of passengers from aircraft.  We also provide for sharing of facilities and gates, and arrange for a sterile area for passengers who have not yet cleared U.S. Customs and Border Protection check points, to the extent practicable.  For full access to the plan, or to learn more, please review the full Emergency Contingency Plan below.
