Tips for finding the cheapest airport taxi include scheduling the taxi in advance, sharing a taxi among multiple people and having your hotel book the taxi for you. However, at some airports, the taxi rates are fixed by local ordinance, meaning no taxis are cheaper than others.
In addition to fixed rates, some airports have designated taxi pickup areas, where each customer must take the first taxi in line. This eliminates the opportunity to choose between taxi companies. For rides to the airport, look at different companies rates online and also look for coupons before booking in advance. Cab sharing provides the most sure-fire way to reduce the cost per person traveling.
