What’s more, the most affordable summer 2021 flight destinations include everything from relaxing beach oases to historic cities. You’ll find that Mexico, Latin America, Florida, and the Caribbean are among the most affordable locales.  

To help inspire your summer travels, we found the ten best summer 2021 flight deals, which range from under $100 to just over $450.

Sugar-sand beaches, turquoise waters, and warm weather all await in Cancun. According to Kayak, the best time to visit is in August, when round-trip flight prices drop by 24 percent, hovering around the $300 mark. However, keep in mind that summer is Cancun’s off-season for a reason: So, while you can expect fewer crowds and cheaper prices, you must be willing to face the hot weather. 

Lisbon, Portugal

From the cobblestone-lined streets to the majestic cathedrals, Portugal offers plenty to see and do — and, if it’s not on your bucket list already, it certainly should be. Even better? According to data from Priceline, Portugal’s capital city is one of the most affordable places to travel this summer. The online travel agency reports that summer 2021 round-trip tickets to Lisbon average at $470: a steep discount compared to summer 2020 ($769) and summer 2019 ($851). 

Fort Lauderdale, Florida

If you can stand the hot weather, summer is the best time to visit Florida, According to Adit Damodaran, an economist at travel booking app Hopper, Florida beach destinations are among the cheapest domestic destinations to visit this summer. You can find round-trip flights to Fort Lauderdale for an average price of $184 (down 31 percent from summer 2020). 

Bogota, Colombia

There’s no better time than now to explore this bucket-list-worthy Colombian city. Although Priceline reports that round-trip flight prices have stayed (pretty much) the same for this summer ($409) and last summer ($412), it’s still a significant discount compared to summer 2019, when average round-trip flights skyrocketed to $612. 

St. Thomas, U.S. Virgin Islands

Embark on an idyllic island getaway to St. Thomas for less: According to Damodaran, summer 2021 round-trip flights average at $333, down 39 and 31 percent compared to summer 2020 and summer 2019, respectively. Plus, since St. Thomas is a U.S. territory, you won’t need a passport to visit (though it is recommended to bring one). Also, it’s worth noting that hurricane season in the Caribbean takes place from June through November, so consider purchasing travel insurance in the event of an emergency. 

Las Vegas, Nevada

The online travel agency also reports that the cheapest flights are available out of Dallas and Denver. 

Santo Domingo, Dominican Republic
