Did you spot my recent article about how to score cheap one way flights? ✈️ FlightList is my new secret tool for discovering cheap routes, within a departure date range. Plus you can also search by country/region for departures & destinations. Powerful! 💪

One useful tool I've found for evaluating different departure and return dates is called FlightList.io. You can quickly scan different travel date ranges, carriers and one way flight options to easily determine the cheapest flight combinations for your trip.
