Pricing on this route moves with the seasons. January, February, and March are consistently the cheapest months to fly, since post-holiday demand drops and Ibiza itself is quiet — many hotels and restaurants close for the winter, so this window suits travelers more interested in the flight deal than the beach club scene. October and November are the sweet spot for people who actually want to experience the island: the summer crowds have thinned, water temperatures are still warm, and fares stay reasonable compared to peak July and August pricing. Booking 3-4 months ahead of these shoulder-season windows tends to lock in the better end of that $2,400–$6,050 range, since consolidator inventory on Delta One and Polaris seats gets pulled first on the cheapest fare buckets.
