How Much Do Flights To Washington DC Cost?

Flights to Washington DC average $218 roundtrip from Europe, with Wizz Air offering the lowest fares at €198 from Bucharest (OTP) to IAD.

Which Airlines Offer The Cheapest Flights To Washington DC?

Compare these three carriers for 2024 routes:

Airline (IATA)	Route	Avg. Price	Duration	Bags Included
Wizz Air (W6)	OTP (Bucharest) → IAD	€198	9h 15m	1 carry-on only
Delta (DL)	JFK → DCA	$275	2h 45m	1 checked bag
Spirit (NK)	ATL → IAD	$149	2h 10m	None

Best Time To Book & Cheapest Months

Book 3-6 weeks ahead for the best fares, avoiding July and December when prices spike 47% above average. January is the cheapest month with $192 average roundtrips (Wizz Air OTP-IAD), while July peaks at $301. American Airlines’ cheapest fares to DCA are $220 in January, but only if booked before November 15. Avoid booking flights on Fridays – prices average 18% higher than Tuesday departures.

Watch Out For These Hidden Fees

American Airlines charges $48 for carry-on bags if not selected during booking – a $20 fee avoided by using their app 24 hours pre-flight. In March 2024, I paid $34 extra on a Wizz Air OTP-MAD route because I missed the free bag allowance deadline. Always confirm baggage policies on the airline’s website before booking, not just the third-party site.

Logistics: Airport Codes & City Transfers

Washington DC has two major airports: DCA (Reagan National, 8 miles from downtown) and IAD (Dulles, 28 miles). Uber from DCA to downtown costs $15-$22 (15 minutes), while IAD requires $45-$55 (45 minutes). The Metro Blue Line connects IAD to the city in 40 minutes for $9.50 one-way. Avoid DCA’s $16 parking fee – use the $7 airport shuttle instead.
