$100 Cheap Flights from Liège

To book cheaper flights from Liège, flexibility is key. Try to be flexible with your travel dates and consider flying on weekdays rather than weekends, as these flights are often less expensive. Setting up fare alerts on travel websites can notify you of price drops. Booking well in advance, or sometimes even at the last minute, can uncover hidden deals. Also, consider flying into or out of alternative airports near your destination, as these might have lower fares. Don't forget to clear your browser's cookies or use incognito mode, as some websites track your searches and may increase prices accordingly.

Generally, the 'sweet spot' for booking flights from Liège is about two to three months in advance. This window allows you to take advantage of airlines' early-bird discounts while avoiding last-minute price surges. However, this can vary depending on the destination and time of year. For peak seasons, booking even earlier—four to six months ahead—might be necessary. Keep a close watch on fare trends and be ready to book when you see a good price, as fares can change rapidly.
