Travelling is a great way to explore the world and gain new experiences. Flights within Europe do not have to be pricey, but there are a few important things you should remember before buying a ticket. How to travel cheap? Time is what matters most. It is good to book airline tickets about 2-3 months before the trip as this is when prices are relatively low. Travel date is also important because weekdays are cheaper than weekends. When to book a plane ticket? Statistics show that it is best to buy an airline ticket in the middle of the week, early in the morning. The reason is that most people browse flight deals and buy tickets in the evenings or on weekends, which translates into increased ticket prices.
