Before booking any tickets, be sure to compare flights on flight comparison websites like Skyscanner. Don’t assume that low-cost airlines will always have the cheapest tickets. With low-cost airlines, you need to pay for checked baggage, and any extra comfort like a possibility to choose your seat, airport check-in, food, drinks etc. So if you actually want to enjoy all these things, sometimes you might be able to find tickets from a regular airline for almost the same price as low-cost but with all the extras included.

Although leg room and the dinner menu might be lacking, your wallet will thank you for the hefty amount of money you will have saved.
