If you're visiting the Gran Canaria, Tenerife, Lanzarote or Fuerteventura and don't have airport transfers included in your booking, here's a nicer option to consider rather than queuing for a cab or trying to figure out the bus service. Maybe you have a coach transfer included but would rather arrive anything up to and over an hour quicker and in a bit more style?
Have a rep/driver waiting for you inside the airport to greet you as you arrive then help you to a private car/coach waiting close by. Not only will you arrive at the resort in more confort and less time but in some cases for a price generally that of a regular taxi* (in Gran Canaria our service is actually more economical than the public taxi service).
On Tenerife we also have a shared/shuttle service available every day, all year round and offer a shared/shuttle service for Gran Canaria Mondays, Saturday nights and early hours Sunday morning - Lanzarote on Thursdays and Sundays - Fuerteventura on Wednesdays and Saturdays. The wait in the airport for other passengers is around 20 minutes (never more than 40 minutes) and transport is usually by minibus with a handful of stops, perhaps 2 or 3 and maybe you're the first?
