Flying from Reagan National
Ronald Reagan Washington National sits 4 miles from the Capitol — one of the most central airports in the United States, with strict perimeter rules limiting most non-stop flights to within 1,250 miles. Metro Yellow and Blue Lines run from the airport's own station directly to downtown DC in 8 minutes for around $2.50. American and Delta have the largest schedules; nearly all flights are domestic. The strict perimeter and slot controls keep DCA fares structurally higher than IAD or BWI.
Arriving in Mexico City
Mexico City International (Benito Juárez) is on the eastern edge of the city, 7 km from the Zócalo.

Mexico City fares from US bases hold steady through most of the year; March and December see modest peaks. AICM is increasingly congested — the new AIFA airport (NLU, 50 km north) handles overflow.
