Why flight prices differ by country
Airlines and booking sites do not sell one price to the world. What you see depends on the storefront serving you: the local currency, local taxes, what the market there will bear, and whatever promotion is running in that country this week. The site decides which storefront you get from a mix of signals, and one of them is where your connection appears to come from.
That is the whole opening for the VPN trick: change the country your connection appears in, and you can sometimes see a different storefront, with different prices, for the same seat on the same plane.
Things also break at inconvenient hours when you are abroad. Both of our picks run 24/7 support over live chat and email, so there is help at 2am: NordVPN and Surfshark both answer around the clock.
How the comparison actually works, honestly
The method is simple: open a private browsing window so old cookies do not give you away, connect through another country, and load the same route again. Compare the final totals, in one currency, fees included. Some routes will show a real difference. Just as many will show a small one, none at all, or a difference that runs the other way.
Your connection is also only one of the signals a booking site reads. Your account country, your chosen currency and your payment card all pull the price back toward home, and a card issuer's exchange-rate fees can quietly eat a small saving at checkout. That is why we call this an experiment rather than a technique: it costs a few minutes, it sometimes pays, and nobody honest will tell you in advance when.
What a VPN does and does not do
Encryption is what a VPN is genuinely for. It also gives you a choice of where your connection comes from, with servers in dozens of countries on either of our picks. What it is not is magic. Two things a VPN does not do. It does not make a connection faster: a VPN will not make slow Wi-Fi faster. Encryption adds a small overhead, so a struggling connection will struggle slightly more with a VPN on. You buy one for protection, not performance. And it does not guarantee that any particular site or service will behave the way it does at home, which is why the table below carries two honest rows you will not find on most pages. The 30-day money-back guarantees on NordVPN and Surfshark are the honest way to test either one on the connections you will actually use.
Recommended VPNs for trying it
NordVPN, best for short trips and month-by-month plans
It is the one for you if you are covering yourself, or you and a partner, and want something simple to run and easy to forget about. One plan covers 10 devices, and the apps are quick to install and easy to switch off and on as you need. Plans run by the month, the year or over two years, all with a 30-day money-back guarantee.
Surfshark, best for long stays and unlimited devices
It is the one for you if one subscription needs to cover everyone. Connections are unlimited, so every phone, laptop and tablet you travel with, and anyone you share a place with, runs on the same plan at once. That suits a stay that stretches to months rather than weeks. It sells the same three terms and adds bonus months on the longer two, with the same 30-day money-back guarantee.
How to choose between them
The differences that matter fit in one table, and the last two rows are there to name two promises you should not believe from anyone, us included.
| Feature | NordVPN | Surfshark |
|---|
| 1 month | $14.99 | $16.45 |
| 1 year plan, total upfront | $65.88 (12 months billed) | $50.85 (15 months billed) |
| 2 year plan, total upfront | $94.23 (27 months billed) | $67.23 (27 months billed) |
| Devices per plan | 10 | Unlimited |
| Kill switch and auto-connect | Yes | Yes |
| Independently audited no-log policy | Yes (2025) | Yes (2025) |
| Money-back guarantee | 30 days | 30 days |
| Guarantees access to any blocked site, anywhere | No | No |
| Makes slow Wi-Fi faster | No | No |
On a single month NordVPN is cheaper. Over a year or two Surfshark is. On everything else the choice is about shape rather than money: 10 devices and a simple setup on one side, unlimited devices on the other.
Setting up before you travel
Do the setup at home, on Wi-Fi you trust, before the airport. Install NordVPN or Surfshark on each device, sign in, and connect once to confirm everything works. Then turn on two settings both apps include: the kill switch, which stops your traffic travelling unprotected if the VPN drops, and auto-connect, which brings the VPN back up when your connection returns.
Both apps work on mobile data as well as Wi-Fi, so a travel eSIM bought before you fly is covered by the same setup.
Final recommendation
Buy a VPN for what it is for: encryption on the connections you will use constantly when you travel, and the freedom to choose which country you connect through. Treat cheaper flights as an experiment you get to run on the side, inside a 30-day money-back window either way.
For a shorter trip, NordVPN is the pick: 10 devices covered and a 30-day guarantee that outlasts most holidays. For a long stay, or anyone who wants every device on one subscription, Surfshark covers unlimited devices.
