Best Flights from DC Area to Scandinavia

I use Google Flights.

If you don't see WOW and Norwegian Air Shuttle among the options, you may need to check on them separately.

Don't forget that you can fly in and out of different cities if you want to. Choose "multi-city" rather than "roundtrip" or "one way".

The Washington and Baltimore region is not well blessed with budget airlines to/from Europe.
You have Icelandair and WOW flying through Iceland from Baltimore and that is it.
The budget carriers are mostly flying from NYC area and Boston.

I would check Iceland Air, WOW, Norwegian Airlines, and SAS. I differ from David's comment - there are adequate choices from the DC area as far as budget airlines go.

I do my best to fly British Airways to Europe. I have my favorite flight and I watch the fee fluctuation. I checked for BWI and a decent one flies out of there: for Sun, Apr 8...for schedule only. I'm sure the summer is likely to show higher prices...most of the time, but if you watch it... Right now this flight is $1099.00. I would just watch it for a month to see how the price fluctuates, but buy before or at 3 months, if and when you like the price. I've gotten some excellent prices by checking at odd times of the day. (I imagine this system should be used for any airline, but I am a BA fan and I pick the flight(s) I like and only watch it(them). No matter which airline you choose, be sure to join their frequent flyer program.

Layover in London LHR3h 30m

1:20 PM+1 – 4:55 PM+1
London (LHR) – Stockholm (ARN)
British Airways 780 · Boeing 767

PS: I usually get my flights roundtrip between $350.00 (but had FF miles) and $650.00(which included preordering seats-a recent phenomenon for me). So don't be turned off by the price(but I don't fly in summer), it just needs watching. As BWI is also essentially on the east coast I would think you could do well as well.

I generally use https://www.kayak.com to search for flight options and then buy my ticket directly from the airline. The ”best” choices out of Dulles are usually the following:
- SAS to Copenhagen - The only Scandinavian city served by a non-stop flight from Dulles
- Icelandair via Keflavik from Dulles
- BA via London - A lot of people don’t like changing at LHR, but BA has quite a few daily flights to Stockholm. This is an option from both IAD and BWI
- United/Lufthansa via Frankfurt

I’ve also flown to Stockholm on United/SAS via Newark, but this is not my preferred route. I prefer to connect at an airport in Europe.

Thanks to all of you for your input. Much appreciated. Diane

Hi, Diane, I don't know if you have made a decision, but I'm taking the RS Scandinavian trip in August and just booked a round trip flight from BWI to Stockholm on British Air for $650, which I thought was pretty good.
