Tips for Flying > Plan your trip

Consider secondary airports: Secondary airports (smaller airports or airports that are further away from the city center) usually have lower airport taxes, which translate into lower ticket prices. When comparing the prices of flights that depart from 2 different airports you need to also take into account the price you pay for transportation to and from the airport (shuttle bus, train ticket, gas, etc).
