When you’ve finally reached a location you’ve wanted to visit for years and it looks exactly like an airport gate in August, a certain kind of frustration sets in. Hot and packed. Exorbitant. Millions of travelers are experiencing this emotion, which is subtly changing how people organize their vacations.
Traveling during shoulder season, which falls between the busiest summer months and the quiet off-season, is no longer a specialty option for retirees and those on a tight budget. Shoulder season reservations increased 20% over 2024, according to booking data from Advantage Travel Partnership. In contrast, summer reservations increased by just 7%. Where travelers are investing their money and, more importantly, their trust can be inferred from the difference between those figures.
The explanation is simple. Summers in Europe are getting harder and harder to enjoy. In June 2024, Greece experienced its first heatwave ever, with temperatures rising above 38°C for multiple days in a row. 66 million people in Turkey were subjected to intense heat last year. By mid-July, places like Spain and Portugal had become so uncomfortable that Intrepid Travel, a small-group adventure company, had completely stopped providing hiking trips there during the busiest summer months. When travel agencies begin planning their schedules based on what passengers can physically endure rather than just what they want, it’s a telling change.
Additionally, the environmental perspective is becoming more and more important. Shoulder season rhythms are well suited to eco-centric travel, which emphasizes reduced environmental impact, real community connection, and seasonal balance. In July, fewer aircraft were jammed onto the same routes. The same tiny streets are not as crowded. Local eateries that, as opposed to two months of chaos followed by quiet, truly profit from a consistent, dispersed flow of customers. It is not an ideological argument. It’s useful. And more and more tourists appear to be coming to that conclusion on their own.
It’s important to remember that overcrowding now has actual social costs in addition to inconveniences. Peak-season saturation has prompted cities like Amsterdam, Milan, and Bali to impose fees, restrictions, or taxes. Milan even went so far as to forbid sitting outside after a specific time during the week. These are not minor adjustments. They are indications that the previous model, in which visitors arrive in August, stay for two weeks, and then depart, is unsustainable for the destinations being visited.
Speaking to investors earlier this year, the president of Delta Air Lines succinctly explained the change: “The peak is getting less peaky and the shoulders are getting stronger.” That kind of language has a certain weight when it comes from an airline. Forecasts made by airlines do not take lifestyle trends into account. They pursue the money.
Less attention is paid to how eco-friendly winter travel fits into this larger trend. Travelers who have grown weary of sun-and-sea formulas are showing a genuine interest in winter destinations, especially in cooler climates that don’t rely on beach weather. In 2026, there seems to have been a significant increase in the “coolcation” trend, which is the deliberate choice of cooler locations over hot ones. It’s still unclear if this is the result of a few seasons of frustration finding a way out or a long-term behavioral change. However, the movement’s direction appears to be constant.
The situation is more nuanced for families. The majority of households are still fixed to July and August by school calendars, which restricts flexibility in ways that individuals and retirees do not. In order to provide families with a practical route to shoulder season travel, some in the industry have started publicly advocating for governments to review term times, shortening the main summer break and extending half-terms in May and October. It remains to be seen if that discussion becomes politically significant.
It’s evident from looking at this data and hearing how operators are changing their offerings that the traditional summer vacation is not going away. Simply put, it is no longer the default. Shoulder season travel has gained popularity because it is, in a very unglamorous sense, the better option rather than because it is clever or counterintuitive. Cooler temperatures, fewer visitors, cheaper prices, and a place with some breathing room. It is not a trend. That needs to be corrected.
