Europe is the trip everyone wants and the one most likely to wreck a budget if you book the obvious way. The trick in 2026 isn't a secret fare - it's choosing the right gateway city and the right month. Do both and Europe becomes affordable again.
The cheapest cities to fly into
Western Europe's marquee hubs are where prices peak. Instead, target Northern Europe gateways, which start around $350-$500 from the US in shoulder season:
| City | Indicative low fare | Why fly here |
|---|---|---|
| Reykjavik (KEF) | From ~$350 | Cheapest transatlantic gateway; free stopovers onward |
| Dublin (DUB) | $350-$450 | English-speaking, great onward budget connections |
| Lisbon (LIS) | $400-$500 | Cheapest Western Europe entry; gateway to Iberia |
| Stockholm / Copenhagen | $400-$500 | Scandinavia base; cheap onward hops |
| Paris / Rome / London | $1,700-$2,100 (peak) | Pricey in summer - arrive via a cheaper gateway instead |
The strategy: fly into the cheap gateway, then use Europe's low-cost carriers to reach your real destination for very little. A $400 fare to Dublin plus a $40 hop can beat a $1,800 direct to your dream city. See the broader picture in our cheapest places to fly in 2026 guide.
The cheapest months to fly
Shoulder season wins: spring (April-May) and fall (September-November) have the best mix of low fares, thin crowds, and good weather. Winter (outside the Christmas/New Year window) is cheaper still. The months to avoid for price are June through August, when demand and fares both peak. Stack the season with the cheapest days to fly (midweek) for an extra discount.
How far ahead to book
For Europe, book 3-5 months out for most routes and 5-6 months for peak summer - the full timing breakdown is in when to book flights. Set a price alert on two or three gateway cities and book whichever drops into the cheap zone first.

- Use a free stopover. Icelandair (via Reykjavik) and TAP (via Lisbon) let you add a multi-day stopover at no extra airfare - two destinations for one fare.
- Fly open-jaw. Into one city, out of another, so you don't backtrack - often cheaper and covered in our Google Flights tricks.
- Bundle a hotel on the expensive nights; package pricing can undercut booking separately.

Europe is only as expensive as the city and month you choose. Fly a Northern gateway in shoulder season, hop onward cheap, and the continent opens up for half the peak price.
