When you search for specific dates and locations, you can choose the class of ticket you want to see results for. Just choose the class you’re interested in from the drop-down menu, and click search! You will see results for one class at a time, so if you want to change the class you are viewing, simply change in the drop-down menu and search again.
At the moment, Skyscanner can only search for premium class fares when you look for specific locations or dates. We’re working on adding this feature to our whole month and year searches, as well as our searches to or from whole countries and even searches to everywhere.
