Tips

Before booking

Compare prices directly on the websites of the various airlines, as for a single destination, prices can vary from one airline to another.
Keep your eyes peeled! Online airlines and airports often have ad hoc promotions.
Be as flexible as possible concerning your dates of travel.
The earlier you book, the lower the price, so try to plan your journey in advance.

Book your ticket directly on the website of the airline so as to receive the lowest prices.
Travel light! The price of checking-in hand luggage is included in the ticket price (subject to certain terms and conditions) and this also reduces the waiting time at check-in.
Check-in online, this can be up to half the price. At the airport, the cost will be higher.
You are not obligated to take out cancellation insurance. In this instance, untick the box when booking and save a few Euros.

Consider checking-in online before departure and after making your booking. If you do this at the airport, you may have to pay a supplement!
Respect the maximum weight per item of luggage authorised by the airline, and you can then avoid paying a supplement for "excess luggage". For sports equipment (golf bags, bicycles, skis, snowboard, etc.), book online, this is much cheaper.
