Take public transit from the airport
Most major cities have direct airport-to-city buses or trains that not only are far less expensive, but often get you to your destination faster than a taxi or hotel limo. The savings can be astounding, even if you have to take a taxi from the train terminal to your hotel. Some examples:
• Dallas: Round-trip taxi fare from DFW Airport, $80 plus tips. Round-trip Trinity Rail Express fare, $5. Savings: $75 plus tips.
• London: Round-trip taxi from Heathrow Airport, $170. Round-trip fare on the Heathrow Express train, $48. Savings: $122.
• Tokyo: Roundtrip taxi from Narita Airport, $416. Round-trip fare on the Narita Express train, $61. Savings: $355.
