The best time to book Air France flights is usually around two to four months before your travel date for international routes, and about six to eight weeks ahead for short-haul trips. Prices often rise as the departure date gets closer, especially during holidays or summer months. Mid-week days like Tuesday or Wednesday tend to show lower fares. If you’re planning to travel during peak seasons, booking even earlier—around five to six months in advance—can help you secure better options. Use fare alerts and flexible dates to find the most affordable tickets.
