Tons of sites do variable pricing, especially in the travel sector. Typically discriminating by device, OS etc.
And you'll often get a discount coupon after staying on a shopping site for a few minutes without interacting.

I’ve tried searching flight prices by remoting into someone else’s computer far away and comparing to mine, and I’ve always gotten the same priced even though I’m not logged in or anything. Ditto for car rentals.
I don’t use travel agents so I can’t say for any other kind of sites.
Unless it’s an opaque rate where you’re bidding for hotel rooms and don’t know which hotel you will get, but you’re forced to buy it once you bid. But I’m talking about publicly advertised prices.
Maybe sites like Priceline or similar places might do stuff like described, but I very highly doubt airlines do, unless they just don’t show availability in some fare codes to specific customers (which I also doubt, with the possible exception of elite status members).
