I don't mean to sound standoffish, but as far as I know this isn't true. I have yet to see real proof that airline companies get you to pay a higher fare by tracking your searches/browsing. While I'm sure you saw a $50 difference, it was likely a slightly different search, which is almost always what happens when people claim they've noticed this. About a year ago, someone on reddit went out and offered a year of reddit gold for anyone that could, there was nobody: https://www.reddit.com/r/LifeProTips/comments/1ekv6e/lpt_bounty_1_year_of_reddit_gold_to_the_first https://www.reddit.com/r/LifeProTips/comments/1ekv6e/lpt_bou... As recently as last week, someone claimed they had reproduced, but they used slightly different search params and ended up with something totally different: http://www.reddit.com/r/travel/comments/2okml5/for_anyone_planning_travel_who_doesnt_use/ http://www.reddit.com/r/travel/comments/2okml5/for_anyone_pl... This myth is rife with anecdotal proof, but I've yet to see anything concrete.

Obviously this is just one more anecdote, but this exact same thing happened to me on the Iberia website about two years ago, while looking for flights from Europe to South America. I kept track of my searches in a spreadsheet, so I know for a fact that the price went up slightly (I think it was by 20€), and went back down immediately when I switched to a different browser. Again, this was unfortunately too long ago for me to have reasonable proof, and it hasn't happened since (perhaps because I now tend to avoid Iberia anyway; they're pretty crappy in other ways as well).

I experienced this just the other day. My father was looking at a price in his computer that I couldn't get (I was getting one that was $500 extra). I erased the cookies of the AA site, refreshed (exactly the same flights, the same days, everything the same) and bam! $500 dollars cheaper.

  I bet you can't reproduce that result ... As someone else here stated, nobody can prove this happens

A couple of weeks ago I were searching for a flight on Easyjet with a friend, and every time we searched for the flight, we got a different price. We tried from incognito, tor and from a phone. Most of the differences were in the cents or at most a few euro, for a 45€ flight.

Your threshold for proof is too high. We're not talking about physics here, these aren't immutable laws to be scientifically investigated, these are systems designed by humans. The wise thing to do is assume they will do anything to screw you until proven otherwise, not the other way around. Personally I don't search airline tickets outside of incognito , and preferably not without VPN or tor protection as well.

This study seems to corroborate https://www.petsymposium.org/2014/papers/Vissers.pdf https://www.petsymposium.org/2014/papers/Vissers.pdf That price fluctuations are more due to activity than user profiling.
