Taking a cab in some cities can cost you an arm and a leg, while in others, fares can be surprisingly good value and provide the best option for getting around.

In this guide American Express Global Business Travel has put together, we take a look at tariffs charged by taxis, across the globe, for getting from the airport to the city center, with train fares for comparison where relevant.

Prices can vary dramatically. In Cairo, fares – at 34 piastres (2¢) per mile – are so low that you could travel 60 miles for what it would cost you to enter the Egyptian Museum. That’s also enough to travel from Cairo International Airport to the museum and back again, according to the SilverDoor Apartments Taxi Price Index. In London, meanwhile, the £8.44 (US$10.75) per mile cab ride from the Tower of London to the Victoria Palace Theatre to see “Hamilton” would set you back the same as the ticket price itself.
