It can also often happen the other way round too. For example, if people from Europe want to fly to the US, and travel via London, the cost of their ticket is often considerably cheaper than those who fly from London directly, particularly on BA. Club class tickets have massive differences in price, and the airlines will cancel your ticket if you try to by pass the system by "pretending" to be located elsewhere. However, if you know someone in Scotland who can book your flight with their credit card, and an address based in Scotland, you can still book the flight in your name. I have done this myself and it works fine. This was recently exposed on the BBC, whereby people who booked the Eurostar train from London to Paris from the American website paid 30% less for their tickets than people who booked the same journey from the UK site. Eurostar's explanation was that it was an example of the "free market". They have now amended their policy and it is possible to book your tickets from whichever site you choose without penalty, so public pressure can work.
