&gt; Skyscanner can also construct somewhat of surprising itineraries by piecing together tickets on multiple separate LCCs that involve non-protected transfers<p>I used to be a big fan of Skyscanner a few years ago, but recently they seem to have dropped the ball and competitors have caught up.<p>In terms of the non-protected transfers there is now Skypicker (<a href="http:&#x2F;&#x2F;www.skypicker.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.skypicker.com&#x2F;</a>), which lets you search airports by distance from a location (so if you need to get to Copenhagen, Denmark you can also search flights to Malmö, Sweden and take the bus which takes ~1hr). It doesn&#x27;t seem to have quite as many low cost airlines, and the UI isn&#x27;t very user friendly.<p>For general flight searches Momondo (<a href="http:&#x2F;&#x2F;www.momondo.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.momondo.com&#x2F;</a>) has a nicer UI and easier access to the filtering options and price estimates. It seems to have the same airlines as Skyscanner too.
