Transatlantic flights don't have to cost a fortune. The difference between paying $400 and $1,100 for the same route comes down to strategy, timing and flexibility. Here's everything you need to know to find the best deals from the US to Europe.
Airlines price transatlantic seats dynamically — the same seat on the same flight can cost dramatically different amounts depending on when you search, what day you fly, and what's happening in the market.
A few fundamentals:
Shoulder season is your friend. The cheapest transatlantic flights are in late September, October, November, early December (before Christmas), and January through March. The worst months for prices are June, July and August.
Midweek vs weekend. Tuesday and Wednesday departures are consistently cheaper than Friday, Saturday and Sunday. This applies on both sides of the Atlantic.
Your departure city matters. Major hubs — New York (JFK/EWR), Los Angeles (LAX), Chicago (ORD), Boston (BOS), Miami (MIA), San Francisco (SFO) — have more competition and often lower base fares to Europe than smaller cities. If you live in a mid-size city, it's often worth flying to a hub first.
Google Flights is the most efficient way to understand the transatlantic fare landscape.
Key techniques:
Grid view: Set departure to your home airport (or "United States" for wider search), destination to "Europe" or a specific country. Use the date grid to see fare variations across months and days. The lowest cells in the grid are your targets.
Explore map: Set your dates and search all of Europe — the map fills with price bubbles for each destination. This is the fastest way to see where the cheapest flights are going right now.
Price alerts: Once you find a route and rough date range you like, set an alert. Google will notify you when prices change.
Nearby airports toggle: Always check this. EWR vs JFK, or BOS vs Providence (PVD), can vary by $100-200.
Skyscanner's "whole month" view is excellent for flexible travelers. Set your departure, set destination to "Everywhere" or a specific country, and view the entire month — cheapest day shown for each potential travel date.
Once you've identified a good fare in a search engine, always check the airline's own website. Sometimes they match or beat aggregator prices, and you earn frequent flyer miles directly.
Norse Atlantic Airways launched transatlantic service with significantly lower fares than traditional carriers. Routes include New York, Los Angeles and other US cities to London, Oslo and other European destinations.
Icelandair serves Iceland (Reykjavik) from many US cities, with connections throughout Europe. Stopovers in Iceland are free — worth building in if you can.
Aer Lingus is not a budget airline but consistently prices competitively on transatlantic routes, especially from US cities to Dublin (which connects cheaply to the rest of Europe).
Award flights on many carriers come loaded with fuel surcharges that can add $400-600 to the "free" ticket. When redeeming points, compare the total out-of-pocket cost against just buying a cheap cash fare.
Use Google Flights Explore to find the cheapest destinations from your city in your travel window. Then decide where you're going based on price — not the other way around. This approach can save $300-500 versus committing to a destination first.
Set a price alert 4-6 months before travel. Track fares weekly. Transatlantic fares tend to drop in waves — there's often a good sale period 2-4 months before departure when airlines run promotions.
Transatlantic last-minute deals exist but are rare and unreliable. If you need to travel in the next 2-3 weeks, accept the higher price or look for sales actively for 3-5 days.
From the East Coast: $400-600 roundtrip to Western Europe is achievable in shoulder season with planning. Under $400 is possible during sales but not reliable.
From the Midwest/South: add $50-150 for less hub competition.
From the West Coast: $500-750 is the realistic budget target for Western Europe; less for Iceland.
London as a hub: Heathrow (LHR) is the most connected European hub for onward travel. If you're going to Southern or Eastern Europe, a connection through London is often the cheapest option.
Cheaper alternatives: Connections through Reykjavik (Icelandair), Dublin (Aer Lingus) or Lisbon (TAP) are often cheaper than London connections.
Long layovers: If your layover is 12+ hours, some airlines allow free or low-cost stopovers. Icelandair's free Iceland stopover is the most famous. Turkish Airlines allows Istanbul stopovers. This can turn a connecting flight into a two-destination trip.
| Departure window | Optimal booking time |
|---|---|
| Peak summer (Jun–Aug) | 4–6 months ahead |
| Shoulder (Apr–May, Sep–Oct) | 6–10 weeks ahead |
| Off-peak (Nov–Mar, exc. Christmas) | 4–8 weeks ahead or last-minute sales |
| Christmas and New Year | 6–8 months ahead |
The key principle: the more flexible you are on destination and dates, the better deal you'll find. A rigid "London on July 4th" search will always cost more than "Europe, anytime in October."
