Have flexible travel plans or looking for alternative routes given the chaos? Check out all the connection possibilities via a super helpful site created by @ismaelyws flightlist.io thanks to @andy_travels for the recommendation #travel #flights
There seem to be lots of sites launching at the moment that promise to find you cheap flights but not many have the professional finish of Flightlist by @ismaelyws #travel #flights
@ismaelyws Just tried out Flightlist for the first time. Really nice idea, well made, and just what I need at the moment 👍
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! 💪
Tips to help you find the cheapest flights from Houston to Porto (HOU to OPO).
❝As someone who works remotely & travels frequently, I always book one way flights and I'm flexible on my departure dates. I look for the best deals. Most sites require you to enter a specific departure date and clutter the page with uneccessary options, images and ads. I want something simple and minimal which allows me to search by departure date range & display a list of flights with the ability to filter according to my needs. So, I built FlightList to solve my own problem & help other travelers who may have the same frustration. It's how I imagine a flight booking site should be.❞
