Welcome to Summer 2025: Where to Go & How to Hack Your Way There

Ready for your most epic, envy-inducing summer yet? You’re not alone. 2025 is officially the year of the “trending destination” — think Tokyo, Zurich, Tbilisi, Paris, San Juan, and more — and the world is cashing in on currency swings, savvy cashback deals, and a buffet of once-unthinkable booking hacks. Whether you’re a points wizard, a family of five, or a solo thrill-seeker, this is your all-in-one blueprint to book smarter, save bigger, and experience more.

2025’s Hottest Trending Destinations (And Why They’re Exploding)

According to Mastercard’s 2025 travel trends report and Expedia’s latest data, here’s where the world is flocking this summer:

• Tokyo – #1 globally, thanks to a weak yen (translation: your dollar goes further than your cousin’s karaoke playlist)
• Zurich & Basel – Up 225% in bookings; Switzerland is having its moment (bring your hiking boots and your sweet tooth)
• Tbilisi – Georgia’s capital is trending for its nightlife, food, and shockingly affordable luxury
• Paris – Always a classic, now with a side of Olympic fever
• San Juan – Caribbean vibes, U.S. ease, and a digital nomad magnet
• Gothenburg, Nha Trang, Reykjavik, Kahului, Punta Cana, Calgary, Tulum – If you like your bucket list with a twist

“Trips to Japan are basically on sale, and have been for over a year because the yen is weaker than it has been in about 38 years.”
— Mastercard Economics Institute, 2025

Your Tactical Booking Blueprint: Flights, Cashback, & VIP Perks

Step 1: Score the Cheapest Flights (& Earn Cash Back)

Pro tip: Don’t just hunt for cheap flights—hunt for cashback and rewards. WayAway is the go-to flight metasearch engine of 2025, letting you compare all the best options across airlines and agencies. Book directly for transparency, set alerts for price drops, and unlock juicy cashback on your bookings.

• Compare every airline and OTA at once (try WayAway)
• Set up alerts for your dream route—pounce when prices dip
• Book in the local currency when possible (currency swings = surprise savings)
• Use cashback to fund your airport ramen or that extra gelato

Bonus: Multi-city routes are a breeze, and you’ll never get hit with hidden fees. WayAway doesn’t sell tickets—they just help you find the cheapest ones. Fly smart, pay less for real.

Step 2: Nail Your Airport Transfers (No Stress, No Surprises)

Destination Deep-Dive: Quick-Start Cheat Sheet

• Tokyo: Book flights in advance and pay in yen for extra savings. Pack an eSIM for seamless navigation. Airport transfer? Reserve on Kiwitaxi and skip the line.
• Zurich/Basel: Switzerland isn’t cheap, but flight deals abound. Book Sunday, travel midweek. Use cashback and pre-book transfers for peace of mind.
