We took the bus to the airport a few weeks ago. It was very easy but involved changing at L'aldea and again to a shuttle bus near the airport. We bought 10 Bono tickets which works out at 10.95 euros a trip, but quite an outlay to start with but we will use them all in the next few months. Not used the return yet, so not sure where to catch the bus. We have a few weeks so we are relying on you out there to keep us informed.
