Should I book one-way flights instead of roundtrip?

Usually no. Roundtrip tickets are typically cheaper from the US to Europe. One-ways make sense if you're planning extended travel or have uncertain return dates.

Are error fares worth chasing?

Yes, but don't plan your trip around them. Follow @SecretFlying or Scott's Cheap Flights for alerts, but have backup plans since airlines can cancel mistake fares.

How much do I save flying into smaller European cities?

$100-300 compared to London or Paris. Cities like Dublin, Copenhagen, or Barcelona often have better deals, plus you can take budget airlines within Europe.

How to Book Cheap Flights from the US to Europe

Book flights 2-3 months ahead, fly Tuesday-Thursday, and use major hubs like NYC or Boston. Expect $400-800 roundtrip if you're flexible with dates and destinations.

Set up price alerts first. Use Google Flights, Hopper, or Skyscanner to track your route 3-4 months before travel. Set alerts for multiple departure cities and flexible dates.
Target the right booking window. Book 6-8 weeks ahead for best prices. Avoid booking more than 4 months out or less than 3 weeks before departure.
Choose flexible dates and airports. Fly Tuesday, Wednesday, or Thursday. Compare prices departing from NYC, Boston, or Washington DC even if you need a domestic connection.
Consider budget airlines strategically. Norse Atlantic, PLAY, and Icelandair offer good deals but check baggage fees. Factor in total cost including bags and seat selection.
Book positioning flights separately. If you live far from major hubs, book domestic flights separately using Southwest or budget carriers. Don't book as one itinerary.
