I am unable to explain airline pricing but I do know some airplane tickets may be cheaper depending on where you buy them or, even better, where you appear to buy them from.\n\nFor reasons I never quite understood, every time I tried to guide a domestic flight overseas, the prices had been at all times exorbitant. But, say, once I was in Bangkok, that same flight that was once $300 would fall to $30 nearly inexplicably. This phenomenon is as a result of a ticket’s point-of-sale – the place where a retail transaction is completed – can affect the value of any flight with a global part.\n\nThough it can be used for normal international flights, it usually works finest if you’re buying domestic flights overseas. To reveal how this scheme works, we ran a one-means search from Cartagena to Bogotá – two cities in Colombia – for June 17 on Google ITA, Kayak and Skyscanner.\n\nTo keep things simple, I will ignore a VivaColombia flight that Skyscanner found as a result of Google ITA and Kayak do not embody smaller airlines in their searches. As a substitute, we’ll be comparing two massive airlines that fly this route, LAN Airlines and Avianca.\n\nGoing the path of least resistance, a Kayak search reveals that the most affordable flight on LAN is $116 and the most affordable flight on Avianca is $137. If we run this precise search in Google ITA with New York City as the point-of-sale, we see those precise numbers Skyscanner returns related results : the most affordable flight on LAN is $114 and on Avianca it is $136.
