Most travelers to South Florida arrive at one of its four airports: Miami, Fort Lauderdale/Hollywood, Palm Beach, Key West. Though they are in different cities, the distances aren't great: the Fort Lauderdale/Hollywood airport, for instance, is just 30 minutes north of Miami; the West Palm Beach airport is about 90 minutes north of Miami. For travelers, this means options - not only in flights, but also in fares. It is not unusual to find flights much cheaper into one airport than another. If cost is an issue, it is worth asking.
