Flight price differences by geography

Hey all,

I've been under the impression that flight prices will vary depending on the country from which you search. However, I didn't seem to find the same when testing.

I used proxies via my web browser in incognito mode (closed/reopened between checks) to check flight prices using Google Flights and Kayak from US, UK, Canada, and Sweden.

Didn't get a cent of difference in pricing.

Has anyone played around with the same? Curious if there's any opportunity to be had, or if maybe some other form of geolocation is screwing up my checks.

Mainly depends on the originating airport so:

- JFK - FRA will be different (most times more expensive) than
- FRA - JFK

so the starting point of your journey makes the difference otherwise, it would be too simple. That's why a lot of trips in premium start in other countries and you have to get a feeder flight to get there etc.
