Flight Booking

Why You Should Always Book Travel During the Opposite Season

Many travelers don’t start thinking about summer flights until the summer, or winter flights until the winter. (Understandably!)

The problem is that summer is the most expensive time of year to book summer flights, and November/December is the toughest time to find a good winter holiday flight.

If you’ve got a cheap-flight-loving heart, the best strategy is, instead, to book during the opposite season.

Always book opposite season

It’s usually around May that I start getting asked how to find cheap summer flights. I do all I can to help—I’m not a jerk!—but I generally have to bite my tongue on what I really want to say: you should have asked months ago.

If you only start thinking about summer flights once summer is almost here, your odds of getting a cheap flight are not great.

Instead, the best approach to getting cheap peak season flights is simple. Book opposite season.

Much like how swimsuits are cheaper in the winter and coats are cheaper in the summer, so too are summer flights generally cheaper when you book them in the winter.

So when you’re at your July 4th BBQ, that’s when you should start looking about winter holiday flights. And when you’re getting dolled up for that New Year’s ball, that’s when you should start looking about summer flights.

The reason why booking opposite season is a good strategy if you’re traveling in peak season? Because it falls within the Goldilocks Windows.

Goldilocks Windows

While there’s no cheapest day or time to book flights—“Tuesday at 1pm” is a myth—there are periods in advance of travel when cheap flights are most likely to pop up. I call these Goldilocks Windows.

If you’re traveling domestically, the Goldilocks Window for when you’re most likely to see a cheap flight is 1-3 months before flying. For international flights, it’s 2-8 months in advance.

But if you’re hoping to travel during a peak time like middle of summer or around New Year’s, you’ll need to add a few months. More like 3-6 months for domestic flights and 3-10 months for international.

Things may be a bit different this year

In normal times, “cheap last-minute flights” is an oxymoron. But as with many aspects of society, the pandemic has temporarily complicated airfare.

We’re seeing far more cheap last-minute flights to Europe than we would in a typical year. But 2021 is not a typical year.

Here’s four reasons why we’re still finding cheap summer flights to Europe this year—including $348 roundtrip to Iceland sent just last week, $531 roundtrip to Denmark, $1,503 roundtrip to Spain in business class, etc.—even last minute:

  1. Families made summer travel plans months ago. Summer flights are normally expensive because for students/teachers/families, it’s one of the only times they can travel. But Europe’s reopening—which didn’t become widespread until June—came too late for many families, who by-and-large made their summer plans months ago.
  2. Lingering hesitancy about international travel. Even as travel rebounds, the number of Americans traveling internationally is still down 60%. As a result, summer Europe flights have far more unsold seats than they did in 2019, and airlines are slashing fares to fill them.
  3. Airlines focus on business class revenue. Decades ago, airlines made most of their money on economy airfares. Nowadays, they make most of their money on revenue sources other than economy fares, things like selling frequent flyer miles, credit cards, corporate contracts, cargo, and yes, expensive business class seats. Long-haul international flights are often quite pricey in business class—normally $2,500+ roundtrip to Europe—which is one reason we launched our Elite service to flag great front-of-the-plane deals. But those pricey business class fares, in effect, subsidize economy flyers and allow airlines to offer <$400 Europe flights.
  4. Vacationers are price sensitive. If flights to Greece cost $1,200 this summer, vacationers will just go to Spain, or Nashville, or take a roadtrip instead. With huge swaths of Europe summer flights still unsold, what’s the easiest way for airlines to entice price-sensitive leisure travelers? Cheap flights.

But the perfect storm that’s enabling currently cheap last-minute Europe flights is unlikely to persist through next year. So if you’re hoping for a cheap summer 2022 flight, the advice still stands: book opposite season.
