The trend is reversed if you want to travel to the Caribbean this year; in 2024, you’ll find the best price only 29 days in advance, while in 2023 you needed to book your flight 56 days early. With the 2026 Winter Olympic Games taking place in February in Milan-Cortina d’Ampezzo in Italy, you should start planning early for your next European travels.
