Cheapest Flights to Europe from the US in 2026

Finding the cheapest flights to Europe from the US comes down to three things: the right airline, the right time of year, and being flexible on your destination. Here’s what actually works in 2026.

Cheapest one-way routes to Europe right now

Not all transatlantic routes are priced equally. These consistently offer the best one-way fares from the US:

Budget carrier routes (under $200 one-way)

• NYC → Barcelona — Norse Atlantic and PLAY regularly drop to $149-189 one-way
• NYC → Berlin — Norse runs this route with fares starting around $129 in off-season
• Boston → Lisbon — TAP Air Portugal treats Boston as a hub, with one-ways from $169
• Miami → Istanbul — Turkish Airlines uses aggressive pricing to fill seats, often $199-249

Mid-range routes ($200-350 one-way)

• NYC → London — The most competitive transatlantic route. Norwegian, Virgin, and even British Airways dip to $229 during sales
• LA → Barcelona — Norse Atlantic launched this route with intro fares under $250
• Chicago → Dublin — Aer Lingus runs frequent sales, especially in shoulder season
• Miami → Lisbon — TAP prices this route well year-round

Routes to watch

• Any US city → Prague — Not many directs, but connecting through Istanbul or Frankfurt often lands under $300 one-way
• East Coast → Porto — TAP’s Lisbon hub makes Porto connections cheap. One-ways from $199 with a short layover

Best months to fly cheap

The cheapest months follow a predictable pattern:

Cheapest (up to 50% less):

• January - March (excluding spring break weeks)
• November (excluding Thanksgiving week)
• Early December (before the 15th)

Good deals (20-30% below peak):

• April - May (shoulder season — great weather, lower prices)
• September - October (summer crowds gone, prices drop fast)

Most expensive (avoid if budget matters):

• June - August (everyone flies to Europe in summer)
• Late December (holiday premium)

A one-way NYC to Barcelona runs $149-189 in February. The same flight in July? $400+. Timing matters more than any booking trick.

Airlines that do cheap one-way to Europe

Budget carriers (your best bet for one-way)

Norse Atlantic — The king of cheap one-way transatlantic flights. They price one-way independently, so there’s no round-trip penalty. Routes from NYC, LA, and Fort Lauderdale to London, Berlin, Paris, and more. Base fares from $109.

PLAY — Icelandic budget carrier with a stopover in Reykjavik. Fares from $99 one-way if you don’t mind the connection. Good for getting to Scandinavia and Northern Europe.

TAP Air Portugal — Not technically budget, but prices like one. Their Lisbon hub connects to all of Europe, and they price one-way fairly. Boston and NYC routes are especially competitive.

Legacy carriers worth checking

Turkish Airlines — Connects through Istanbul, which makes it a natural for reaching Southern and Eastern Europe. One-way pricing is surprisingly good, especially to Istanbul itself.

Icelandair — Free stopover in Iceland on the way to Europe. One-way fares from $179, and you get a free mini-trip.

Chinese carriers (China Southern, Hainan) — If you don’t mind a longer connection through China, these airlines occasionally offer one-way fares to European cities for under $300. Less convenient, but hard to beat on price.

The open-jaw strategy

This is the move for nomads and backpackers: fly into one city, leave from another. No backtracking, no wasted time.

Example: Fly one-way NYC to Barcelona for $179 on Norse Atlantic. Spend a month traveling through Spain, France, and the Balkans. Fly one-way from Istanbul back to the US for $249 on Turkish Airlines.

Total: $428 for two one-way flights. A comparable open-jaw round-trip on a legacy carrier? $600-800.

Two one-way tickets give you more airline options, more flexibility, and usually a lower total price than an open-jaw booking.

Booking strategies that actually work

1. Book 2-4 months out for international

Unlike domestic flights where last-minute can work, transatlantic fares reward advance booking. The sweet spot is 2-4 months before departure for budget carriers, 1-3 months for legacy airlines.

2. Check nearby airports

Flying from Newark instead of JFK, or Oakland instead of SFO, can save $50-100. Same goes for the European side — flying into Girona instead of Barcelona, or Bergamo instead of Milan.

3. Use positioning flights

If you’re in a smaller US city, don’t book a single ticket through to Europe. Book a cheap domestic one-way to NYC or Boston, then a separate budget carrier flight to Europe. Two cheap tickets beat one expensive one.

4. Watch for error fares

Airlines occasionally publish fares at a fraction of the intended price. These “error fares” to Europe can be as low as $100-150 one-way, but they disappear within hours. The only way to catch them is through real-time alerts.

Bottom line

The cheapest flights to Europe from the US right now are on budget carriers flying one-way from East Coast cities. Norse Atlantic and TAP are your best bets for sub-$200 fares. Fly in shoulder season, be flexible on your exact destination, and use the open-jaw strategy to avoid paying for a return you don’t need.
