- Love that I can set my location and it suggests me dates with the cheapest airfares.I'd also highly recommend Skyscanner! You can filter the results with different criteria, so if you only want direct flights, you can get rid of any that involve transfers. It also lets you search for nearby airports to find the cheapest deal. My only criticism is that Skyscanner doesn't take into account certain fares - for example, SAS does 30% discount for under 26s, but Skyscanner doesn't show this.
- the only one service which shows you flights with hidden-city optionDefinitely Skiplagged. I've saved hundreds of dollars on flights with it... for example, turns out a flight from Cleveland --> Houston --> Cancun is $300 cheaper than a flight from Cleveland --> Houston. That's what Skiplagged can show you. It's wonderful.
