Yes! September is part of the shoulder season in the Northern Hemisphere. This means it's between the peak and off-peak travel seasons.
Off-peak flights are cheapest, but the shoulder season is still very affordable.

Your September flights can still be kept very affordable when booked through Alternative Airlines. Our buy now, pay later partners, easy filter system, and promos and discounts mean that no matter the season, you can travel for less.
