To secure cheap flights from Boston Logan International (BOS) to Amsterdam Airport Schiphol (AMS) in February, start monitoring fares 6–10 weeks before departure and be flexible with midweek travel dates (Tues–Thurs). Use fare aggregators, set Google Flights or Skyscanner alerts with keywords like "BOS to AMS February deals," and consider one-stop itineraries via London, Paris, Frankfurt, or Reykjavik to shave costs. Book early-morning or late-night flights for lower prices, and sign up for airline newsletters (KLM, Delta) to catch flash sales. Consider travel credit card points, airline miles, and bundling hotel + flight for extra discounts.
