Travel is on the uptick which comes as welcome news to both the industry and those who have been at home, waiting to get back out into the world. While local travel is booming and remote getaways are still trending upward, international travel is beginning to pick up, as well, especially as the summer goes on. Over the last year, we've seen things such as 'flexcations' and quick weekend getaways just for a change of scenery, but what about longer, more semi-permanent stays?

According to a report published by Airbnb, the company's data is showing that not only have people booked rentals for 2021 around the world, but they're also renting them for longer. So, it turns out that international travel and longer vacations are going hand in hand, at least for the time being. Anything over two weeks is considered a long-term stay, and rentals are the best way to do it. According to Airbnb's data, these are the cities that are seeing long-term rentals skyrocketing, and the 'why', according to us, they're seeing so much popularity.

New York City, New York

New York City has always been captivating to travelers and it's still known as the best and most diverse city in the U.S. Therefore, it's not overwhelming surprising that so many people have it on their itineraries for summer 2021. What is surprising is that, according to Airbnb, 62% of all the rentals booked for the city are long-term stays, which means a month or longer.

Interestingly enough, the majority of the people booking these long-term stays are actually New Yorkers, which means they could be looking for an urban getaway from Upstate or out on Long Island. Renting a place long-term in the city affords locals a chance to theoretically go away whenever they want via a train ride, without having to repeatedly rent a place every week.

Seattle, Washington

Seattle (along with Los Angeles) is in second place for the most long-term bookings. There, roughly 40% of travelers have a vacation booked for a month or longer. While there's no data on where travelers are from, chances are, if the trends from the East Coast apply, renters are likely also from the West Coast.

Seattle is a popular Pacific Coast city destination, in general, but it's not one that's usually tied with Los Angeles for top billing - with so many people looking to commune with nature, this could be why a city rental in such a state is so appealing.

Berlin, Germany

Airbnb's travel report also states that, when polled, 74% of customers revealed that they'd like to live in a place other than where their employer is located post-pandemic. Since so many people have started permanently working from home, the decision to make this change has been an obvious choice for some, and cities such as Berlin allow for easy commutes in and out of the country.

Since last year, Airbnb has been a fairly consistent means of finding work-from-home vacation rentals, according to the report, with many combining a change of scenery with their new flexible work lives.

Paris, France

Working from a long-term rental property is one way to see Paris, and there are plenty of places to do it from. As one of the most popular destinations for travelers heading to France, it's not surprising that many people are swapping out coffee from their kitchens for a croissant and café au lait from a bistro in Paris.

This city, like Berlin, makes it easy for travelers to set up shop wherever they go, and work from practically anywhere throughout the city.

Melbourne, Australia

What is surprising is the fact that so many people are booking long-term stays in a country that might be halfway across the world from their homes. According to that same Airbnb report, the reason for many people traveling long-term is due to family.

Some expats or family members who were relocated prior to the pandemic had no choice but to remain stationary, and those who live in other countries are now taking advantage of spending long durations of time with them. This likely accounts for many of the long-term bookings around the world and visiting family are one of the top priorities of many, as well as one of the first things people are planning on doing once vaccinated.

Mexico City, Mexico

For those in the U.S., Mexico has been open for quite some time in 2021. With a passport, tourist permit, and Mexican auto Insurance, visitors are free to cross the border if they happen to live near it.

This makes travel to Mexico far easier than travel to other countries right now, including Canada, which currently has major closures at its borders. Mexico City is a popular tourist destination but now that pandemic numbers have declined, it's also becoming a popular place for people to temporarily live, well.
