The BBC conducted an experiment using two computers, a deleted the cookies, and the other is not. According to the journalist, Harry Kretchmer, who conducted the test, it became clear that “the computer with cookies was statistically more likely to provide a price a little higher.”
Kretchmer says that during the test they looked for repeatedly on both computers at the same time a trip for a family of four people from London to New York in mid-August, in high season. In the search included flights and hotels.
The samples included sites of high demand such as Booking.com, Opodo and Expedia. The BBC confirmed each of the results to seven times on each page for five hours. The results were not uniform; for example, in Booking.com there were no differences between the computer ‘clean’ and that she had cookies.
But on Opodo and Expedia found differences in the prices of between 1.5 and up to $ 30 per person, which would involve extra outlay of up to us $ 120 per family.
“At Expedia, four of seven results in the computer with cookies were more expensive. At Opodo, five of seven. But sometimes, there were lower prices in the computer with cookies, so there is not an exact law, although seems to make a difference,” says Kretchmer.
The companies said that the prices may vary “for various reasons” -without giving details – and that you understand that this may worry some customers.
