The 45km Oslo airport to town journey costs £67.77 and the 24km drive from Heathrow into London's West End comes costs on average £57.
However, on a cost per kilometer basis, the cab ride from Copenhagen Airport actually works out as the worst value for money, because at £33.33 for an 8km journey, the true cost is £4.17 per kilometer.

Dent in your holiday budget
Simon Phillips, head of retail for No1. Currency, said: "Even though the pound is almost 3% stronger against the euro compared to 12 months ago, [a taxi] is still an extra cost that could make a large dent in your holiday budget if you're not careful or prepared.
"If the airport to city centre taxi ride is particularly expensive, like in Milan, then taking the bus or train may be the better or only option so it's worth checking out the local transport system in advance. Alternatively, you might be able to book a taxi before you travel, which could work out significantly cheaper than flagging down a taxi outside the airport."
