Can you buy the same flight for less if you use a VPN?

Yes, but it's hard. Eg for a while on Flightfox when you had flight hunters (not part of their system any more), one trick was to look for flights on Brazil sites, as their taxes were often lower. However you needed a national ID and some other complications.

I run Beat That Flight in Australia and have seen OTAs (online travel agencies) show different prices to what is shown on say Jetstar NZ's website, because it doesn't take into account Jetstar Australia's sales. OTAs can see both, and can find the discounts.

Furthermore, sometimes, say, Qantas/Virgin in Australia might have a discount code not eligible for their overseas websites.

Hard to give an example because prices always change, but the most common discrepancy is on Jetstar on Fridays, when either the AU/NZ sites run their "Friday Frenzy sales" and sometimes by combining the two on a 3rd OTA website found via my site, I can beat both their official prices combined.

[We had a similar question 4 years ago where I tested with a VPN and couldn't see a difference, but that was just with one example. There may well be other sites/places where it does happen)
