In London, it’s a passenger use tax, and it’s levied by the United Kingdom on anybody who is leaving for the United States. The tax is said to be unavoidable, but In many cases, it can be as much as $200-$300. But it is avoidable, and here’s how you do it.

You can buy an open-jaw ticket from the U.S. to London and Paris back to the U.S. And how do you complete the triangle? You take the Eurostar to Paris. You save the money on the taxes and that’s how you use your train ticket. Leave a day early in London, and your hotel is about the same as it’s going to be in London.

Two countries for the price of one is not a bad deal.
