This summer’s cheap flight tickets make it most affordable to travel to five cities globally.

In usual circumstances, the best deals on summer flights are often sold out by the end of May and early June. However, the situation in 2025 is different from previous years. Due to various factors, there are still discounted airfares available at the moment.

According to a report by CNBC on May 25th, travel expert Katy Nastro from the U.S. booking website Going told CNBC, “There is some uncertainty in the economic situation, so people may hesitate to book flights. With an increase in flights on the schedule and a slight drop in fuel prices, this is simply the perfect time for cheap flights.”

For those who are looking to book a last-minute summer vacation, Nastro has one piece of advice, “If you want to book a flight but haven’t done so yet, then August is your best target month.”

If you are looking for a summer travel destination that won’t break the bank, Going’s experts have listed five cities where airfares are below average and will remain low until autumn.

Experts suggest that due to a nearly 20% decrease in the number of visitors entering the U.S. from Canada, there are special discounted flights to various destinations in Canada during the summer. Flights to Calgary are widely available. The average round-trip discounted fare starts at $258, and from some cities, prices can be as low as $142.

Experts suggest that if you want to spend a less humid and more comfortable holiday, head to the Southern Hemisphere. The average airfare to major cities in the Southern Hemisphere is around $355, slightly higher for smaller cities at around $699. Prices range from $600 to $1,000. The exchange rate of the U.S. dollar to the Brazilian Real is quite favorable, making it affordable for most budgets.

Experts comment that while Dublin is not the cheapest travel city in Europe, it is certainly not the most expensive either. From most major cities, summer peak prices for flights to Dublin range between $300 and $400, with an average round-trip fare for all cities at $511.

Experts suggest that the average round-trip airfare to coastal cities in Mexico like San Jose del Cabo is around $354, with even lower-priced tickets available. Flights departing from Austin start at $292.

Experts suggest that the Northeastern United States is particularly charming in summer, from the cobblestone beaches of the Connecticut South Shore, stretching all the way to cities in Rhode Island and Maine. The average round-trip airfare to cities such as Bangor, Boston, and Hartford in New England is $149.
