WOW Airlines is currently offering round trip flights from Chicago to Reykjavik, Iceland for $199 round trip. A few days ago they had excellent deals from various U.S. cities to Iceland for under $275. This deal is the best I’ve ever seen from Chicago to Iceland. If you do a quick search on Google Flights, you will see multiple departure and arrival dates for October and November for $199. You can see an example below:
This deal probably won’t last long so if you’re interested in visiting Iceland and have some flexibility over the next month or two, this would be a great time to jump on this offer.
