Record TSA crowds, heat waves: summer 2025 travel survival tips
Summer 2025 is breaking travel records: June 23 saw 2.99 million TSA screenings in a single day, and eight of the ten busiest travel days ever occurred in the past month. Paris hit 111°F (44°C), Europe's hottest June on record. Two heat-driven disruption waves — around June 21 and June 25–26 — each snarled thousands of European flights in 24 hours. The World Cup is adding extra pressure on already crowded North American cities.

This summer has been absolutely relentless for travelers. It's not just the sweltering heat in cities like New York and Chicago that's causing stress, but major cities have been crowded in a way that compounds the heat. Additionally, June 23 set the all-time record for TSA screenings (2.99 million in a single day), eight of the 10 busiest travel days ever occurred in the past month alone and the World Cup is taking place across most major North American cities, meaning that already crowded cities are even busier.
And you're not beating it with a trip across the Atlantic. Europe just logged its hottest June temperatures since records began, with temperatures reaching 111 Fahrenheit in Paris. Two separate heat-driven disruption waves — around June 21 and again June 25–26 — each snarled thousands of European flights in a single 24-hour stretch.
It's been a lot, and we're not even halfway through July. With TPG's team being on the road all summer, here's what we're doing to beat the heat and manage the crowds — and keep our sanity while we jet set.

First and foremost: Stay hydrated
BERTRAND GUAY/AFP/GETTY IMAGES We've all been there. You land in a new city, drop your bags and immediately head out to explore. Two hours later, you realize you haven't had a drop of water. When it's 100-plus degrees outside, this is downright dangerous for your health. So, do yourself a favor and pack a reusable water bottle with you this summer.
TPG's managing editor of hotels and destinations, Ellie Nan Storck, packs a collapsible water bottle with her in her backpack whenever she travels. These break down easily so you're not lugging a rigid plastic bottle around. Storck recommends the Salomon Soft Flask , which has treated her well on dozens of recent trips. Given it's just $22, it'll pay for itself after just a few refills (yay, no more $5 water bottles on the Vegas Strip!).
Storck also packs electrolyte packets, which matters more than people give it credit for. When it's hot enough that you're sweating through a city day, you're losing more than water. An electrolyte boost can make all the difference in how you feel.
One more hydration tip that catches a lot of people off guard: Flights are actively dehydrating you. "Airplanes dehydrate you way more than you might think," says TPG social media manager Annie Black. "I knew they were dry, but I didn't know they were that dry." Start drinking water hours before you even board, and you'll get off the plane without feeling like you've spent the day in the desert.
Check your credit card benefits at events
CAROLINE TANNER/THE POINTS GUY Storck and TPG's editor-in-chief Nick Ewen recently attended the Miami Grand Prix. It was sweltering, and the duo was lucky enough to spend an hour in the American Express Lounge, thanks to their Amex Platinum cards. This had complimentary water, air conditioning and free lunch that kept them cool and well-fed during the event.
With that in mind, check if your credit cards have similar benefits at concerts, sporting events and conferences. These spaces give you a place to beat the crowds, cool down and enjoy a bit of quiet time outside the event's chaos.
Also note that Clear members have access to expedited security lines at airports, as well as at a number of arenas and stadiums around the country, which can significantly speed up your travel experience. I recently used Clear to get into Yankee Stadium and saved at least 20 minutes in the heat.
The right travel gear goes a long way
A portable battery-powered fan used to feel like something only an over-prepared tourist would carry — but not in this heat. Senior writer Ben Smithson was a skeptic until he recently went to a comedy show in a historic building. "I used to think carrying around those battery-powered portable fans was a bit extra," he says, "but I went to a comedy show in a very un-AC-ed historic building and I (and several others) had them perched on the back of the seat in front." It made all the difference throughout the show.
On trains and planes, TPG's senior newsletter editor Colin Hogan has a different tactic: a cooling migraine mask. "This cooling migraine mask has been a godsend in a hot plane or train cabin," he says. "I originally got it for migraines but have honestly used it more for travel. It cools my whole head and tunes out stimulation, while also making me look like the kind of ridiculous person no one wants to talk to — a win-win, IMO." It's hard to argue with that logic.
Lastly, TPG writer Rachel Craft recommends bringing a pack of bandages on the road to prevent blisters. When you're hot and sweaty, friction increases, which makes blistering more likely. A bandage is a cheap and easy way to fix a problem that could otherwise take you out of commission for the rest of the day.
Do your research before you book a hotel
It's one of those things that sounds obvious until it happens to you. "There is literally nothing worse than trekking through a heatwave with all your luggage, getting to your hotel/rental in the hopes of cooling off, and realizing that the place you booked doesn't have working AC as a respite," says TPG editor Madison Blancaflor.
You can find this info on hotel websites and online travel agencies. Likewise, Airbnb and VRBO listings will specifically note whether the property has air conditioning, so be on the lookout when you're headed to Europe, especially.
If all else fails, head somewhere colder
Head to Australia to beat the heat. CLINT HENDERSON/THE POINTS GUY TPG's cruise lead Gene Sloan's answer to a brutal summer is simply to leave it behind. This summer, he went on a trip to Australia, where the seasons are reversed (compared to his home in the U.S.) — and July is the middle of winter. "My summer PTO was in Australia , where the seasons are reversed and it was blissfully cool," he says. "Not cold. Sydney and the coast were very pleasant in the 50s and 60s during the stay. Some days all the way up to 70."
I did this just last weekend, when my wife and I went to Nova Scotia for the second time. It's our new favorite place to visit in July , with mild temperatures (think mid-70s at the highest) and very few crowds, even in touristy areas like Lunenburg.
Those seeking colder weather can also consider traveling to Patagonia, South Africa, Scandinavia and New Zealand.
Bottom line
Traveling in the summer can be a challenge, especially during a heatwave. But if you plan your trip carefully, you can avoid the worst of the heat. Stay hydrated, check your credit card benefits and make sure you're staying somewhere with air conditioning. And if you want to get out of the heat (and crowds) entirely, headed south of the equator and enjoy mild winter weather.
