Perhaps. >If you visit the airline's site multiple times, you are not penalized (price-wise) for that. >However, given well-known yield management techniques, you are likely to see the price rise over time. >Variations such as the modulation on the time of day make generalizable comparisons harder. >If you browse the site in a fresh browser, you may see a different offer but the resulting price is substantially similar. This kind of makes sense as a marketing ploy — try harder to attract the comparison shopper, but sell them the same ticket in the end. http://skeptics.stackexchange.com/questions/9597/do-ryanair-use-cookies-to-raise-the-price-of-their-tickets-after-you-have-visite http://skeptics.stackexchange.com/questions/9597/do-ryanair-...
