A travel hack involving VPNs is going viral again, with travelers claiming they’re finding cheaper flights, hotels and vacation packages by changing their virtual location before booking. The idea is simple: some travel websites adjust prices based on where you’re browsing from, meaning users in lower-income countries can sometimes see lower rates for the exact same trip. Many travelers say switching their VPN to countries like India, Vietnam or Brazil, while clearing cookies or browsing in incognito mode, can unlock better deals. Experts say it’s not illegal on most platforms, but some airlines and hotel sites may flag bookings if payment details don’t match the country used during checkout
