Summer travel searches are heating up, with searches up as much as 70 percent month over month (as of the last seven days). As pent-up demand for travel takes flight, KAYAK is releasing its 'Return to Travel' Hacker Guide focused on where to go as restrictions ease.

Key highlights from this year's guide include:

• The Caribbean is calling all Vaxicationers. Looking at the last 7 days, the Caribbean is showing great signs of recovery with travel search interest down only 16 percent compared to the same in 2019, likely due to eased restrictions for vaccinated U.S. travelers announced earlier than most places. In fact, out of the top 10 most searched for destinations open to U.S. tourists, five are within the Caribbean including Cancun, Punta Cana, Montego Bay, Aruba and The Bahamas.


• Solo travelers are headed South. Despite the pandemic, interest in solo travel is still top of mind for many with 68 percent of searches for solo travel in the first three months of 2021, particularly to South America. This is likely due to eased restrictions and wallet friendly airfare prices, which are down 14 percent over the last 7 days (4.27 - 5.3) compared to the same time period in 2019 - the cheapest of any region. Cartagena, Lima and Medellin in particular are attracting the largest number of solo travelers with at least 80% of flight searches for one person to all three cities.


• Group travel is booming. Whether it's your group of best friends or a family of 3+, groups are reuniting in places with sun, sand and warm weather - not to mention plenty of outdoor activities. Las Vegas, Orlando and Honolulu are among the most searched for destinations for parties of three or more.


• Americans are eager to travel overseas. Recent news that vaccinated American tourists will likely be able to visit the EU this summer caused travel searches on KAYAK to spike indicating Americans are eager for borders to reopen and travel overseas. Even prior to the news, some European destinations were starting to pop, European destinations that saw the biggest spike in searches month over month for travel anytime include Dubrovnik (searches up 205 percent), Zurich (searches up 167 percent), Prague (searches up 144 percent) and Reykjavik (searches up 143 percent).
