It's perfectly legal to offer different products or different prices to different markets. What's not legal is blocking someone from accessing a market just because it's not their "home" market.
Skyscanner has come up in this discussion, and full disclosure: I'm an employee. But this is an entirely personal comment.
Skyscanner has a lot of different market-based websites, for example https://www.skyscanner.de and https://www.skyscanner.fr. We don't geo-block, though: wherever you are, you'll have full access to any Skyscanner website, and we'll happily give you whichever market, locale, and currency triple you ask for. And we pass on the underlying market-based prices that we're given. So if you want to know whether different markets get different selections of flights, or different prices for the same flight, it's relatively easy to look and find examples.
Amazon is the same: you'll get different products and prices on de and uk, but if I'm willing to pay shipping then Amazon is willing to sell me stuff from Germany even though the UK left the EU and it's legal for them to block me or give me different prices. Which was very useful when I needed radiator thermostat adapters a couple of months ago.
