A lot of airports have train stations attached as well, so consider public transport if you want to save a dollar or two.
Solo travelers are way more likely to be ‘taken for a ride’ at the airport by unscrupulous taxi drivers, so do your research before you arrive. Make sure you get a cab from the airport/station taxi rank – if you’re not sure where to go, just head to the information desk for help. Touts tend to hang out in the arrivals area and promise cheaper rates, but can often be dodgy. When you get to the cab rank, ask the driver to use the meter or request a cost estimate before you hop in the car – if it’s way higher than it should be, pick another vehicle.
