Cheapest Time to Fly to Spain (and the Most Expensive)
The cheapest time to fly to Spain is usually winter and select shoulder-season weeks—while summer, Semana Santa, and late December are the priciest.
Flights to Spain can swing a lot by season—mostly because demand spikes during summer vacations, major spring holiday weeks, and year-end travel.
If you’ve got any flexibility, you can often save hundreds by targeting winter and calmer shoulder-season stretches, then skipping the big “everyone’s traveling” weeks.
Quick Take
- Cheapest time to fly to Spain: mid-January–early March, late April (some weeks), late September–October, and mid-November–early December
- Most expensive time to fly to Spain: Semana Santa (March/April), June–August, late December–early January, and peak long-weekend weeks in late spring
Cheapest Time to Fly to Spain
The cheapest flights to Spain usually show up when fewer people are crossing the Atlantic, airlines have more open seats to fill, and you’re outside school-break travel patterns.
Mid-January to Early March (Post–New Year Dip)
After the New Year rush fades, airfare often drops and options open up—especially if you can avoid weekend-heavy schedules. This is one of the most reliable windows for lower fares into major gateways like Madrid and Barcelona.
Money-saving tip: Try Tuesday–Thursday departures if you can shift dates.
Exception: Big convention weeks in Madrid or Barcelona can tighten nonstop seats and push prices up.
Late April (Select Shoulder Weeks)
Late April can be a sweet spot if your dates fall after the spring holiday surge but before early-summer pricing starts creeping in. It’s not always “cheap,” but it’s often more deal-friendly than May and June.
Money-saving tip: Price-check both Madrid and Barcelona, then compare the cheapest onward connection to your final city.
Exception: If your dates slide into early May, fares can jump quickly.
Late September to October (Post-Summer Cooldown)
Once peak summer travel fades, prices often loosen up—especially after the first wave of fall travelers is done. This is a great window if you want solid weather without paying summer-level airfare.
Money-saving tip: Look at “open-jaw” trips—fly into Madrid and out of Barcelona (or vice versa) to cut backtracking.
Exception: If a major event lands on your exact dates, hotel demand can indirectly raise flight prices too.
Mid-November to Early December (Pre-Holiday Lull)
This is a calm stretch before Christmas and New Year travel ramps up. You can often find lower fares while still getting a good selection of flight times.
Money-saving tip: Keep your return flexible—fares often climb as mid-December gets closer.
Exception: The moment school breaks begin, pricing usually shifts into holiday mode fast.
Most Expensive Time to Fly to Spain
The most expensive time to fly to Spain is when transatlantic demand stacks up—summer, major spring holiday weeks, and year-end travel are the main drivers.
March to April (Semana Santa)
Semana Santa (Holy Week) can push prices up sharply, especially when it lines up with US spring breaks. Flights and the best nonstop seats can sell quickly.
Peak within peak: Departures right before Holy Week and returns right after it tend to be the most expensive.
June to August (Summer Peak)
This is the toughest stretch for deals. More families travel, more people need weekend flights, and the best itineraries disappear first.
Peak within peak: Late June through early August is often the roughest run for pricing.
Late December to Early January (Holiday Rush)
Christmas and New Year travel raises fares across the board. If you want this window, booking earlier usually beats waiting for a drop.
Peak within peak: Late-December departures and early-January returns are usually the highest-priced combos.
Late May (Long-Weekend and Early-Summer Build)
Late May can surprise people—pricing often rises as the summer season warms up and long-weekend demand stacks up.
Peak within peak: Friday/Saturday departures and Sunday returns tend to price higher than midweek.
On a Budget But Want Good Weather in Spain?
If you want comfortable conditions without peak-season airfare, these windows are usually your best bet:
- Late April (select weeks): Warmer days in many regions, with better deal odds than May and June
- Late September to October: Great timing after summer demand fades—often one of the best “value weather” windows
- Early December: Cooler, easy to move around, and often cheaper than late-December holiday travel
Best Booking Window for Cheap Flights to Spain
If you’re aiming for the cheapest time to fly to Spain, start watching early and grab a solid fare when it appears—transatlantic pricing can move fast.
- Low/shoulder seasons: start tracking 2–5 months ahead
- Popular seasons: start tracking 4–7+ months ahead
Extra tip: Spain deals are often best into Madrid (MAD) or Barcelona (BCN)—then you can add a low-cost flight or train to places like Seville, Valencia, Málaga, or Mallorca.
