Tenerife is a Spanish island reached only by either plane or boat.   There are two airports, depending on whether you want to reach Tenerife Norte or Tenerife Sur. The official website for Spain's airports is http://www.aena.es/csee/Satellite/Hom...      It is in English and you can check flights, car rentals, stores, etc.

Visitors wishing to fly to Tenerife Norte will use Los Rodeos Airport (TFN). Located 17 km from the centre of Santa Cruz, this single-terminal airport is convenient for travelers who will be heading from the airport to areas including Tacoronte, Icod de los Vinos and Puerto de la Cruz.   From the airport, visitors can rent a car, hire a taxi or use the public bus system to get to their hotel destination.   More information about Los Rodeos Airport can be obtained by visiting http://www.121airports.com/tenerifelo... .  

Visitors wishing to fly to Tenerife Sur will use the Reina Sofia Airport (TFS). This is the larger of the two airports on Tenerife and is often used even by visitors planning to head to the northern part of the island, as few international flights use TFN.  From TFS, it is a very short drive to the southern or southwest villages of the island, including Los Cristianos, Las Americas and Los Gigantes.  Once reaching the Reina Sur Airport, visitors can rent a car, hire a taxi or use the public bus system to get to various locations throughout the island.   More information about the Reina Sofia Airport can be obtained by visiting http://www.121airports.com/tenerifere... .

On departure day you can check baggage in and head back outside to sit, relax and finish any locally bought  "liquid refreshments" and snacks beneath the shade afforded by the avenues of palm trees. Do check the departure info screens regularly though, and allow time for security checks.
