You'll need to decline all extras to get the lowest price. WOW basic fares only include one small personal item (small backpack, purse, etc.). Carry-on bag fees start around $45-$50 each way. Checked bag fees start around $55-$68 each way.

Even with WOW Air's many fees, some of these routes don't see that many flash sales on other airlines and WOW Air can still often be the best price after you add in any extra fees that are necessary.

One interesting thing I noticed is that if you click through and book via this secret flexible calendar link, you'll be able to get a lower $35 each way carry-on bag fee on all routes. This can potentially save up to $30 roundtrip in bag fees, so give it a go. Plus, it will be easier to find the lowest available prices using this link. You'll just have to click the "search again" button to adjust the search for your desired route.

As an example booking, I found seats departing Boston BOS on Monday, February 11, returning from Reykjavik KEF on Saturday, February 16, for $149 roundtrip.
