How to Find Cheap Flights from the US to Europe
Use Google Flights to track prices 3 to 6 months in advance and remain flexible with your destination hub. Book mid-week flights on Tuesdays or Wednesdays, as these consistently offer the lowest base fares compared to weekend travel.
- Set up Google Flights Tracking. Enter your departure city and your broad destination (e.g., 'Europe'). Toggle the 'Track prices' switch to receive email alerts when prices drop. Do this at least 120 days before your intended departure.
- Leverage 'Hidden' Hubs. Don't fly directly into expensive cities like London or Paris if they aren't your final destination. Use the 'Explore' map feature on Google Flights to find the cheapest airport to land in, then take a budget airline (like Ryanair or EasyJet) or a train to your final stop.
- Book at the 'Sweet Spot'. For international flights, the best deals appear between 3 and 6 months before travel. Avoid booking last-minute (less than 21 days out) unless you are comfortable paying a significant premium.
- Check Alternate Airports. If you live near a major hub, check flights from secondary airports within a 3-hour drive. Sometimes flying out of a different city can save you $200+ on long-haul routes.
- Are 'incognito' searches actually cheaper?
- No. Airlines do not change prices based on your browser history or cookies. Use Google Flights or Skyscanner for the most accurate data.
- Is it cheaper to book two one-way flights?
- Sometimes. Compare the price of a round-trip ticket versus two separate one-ways on different airlines. Occasionally, a 'hacker fare' can save you money, but be careful with layovers.
