But the state-operator AENA has said that all 46 airports and two heliports within Spain will be able to provide the service by the end of 2015, providing free Wi-Fi to an estimated 200 million passengers a year.
However, the free Wi-Fi service operated by Eurona Telecom will be limited to 2 megabytes of data for free with those wishing to upgrade to purchase 10 megabytes within a 24 hour period at a cost of €4.90.
Frequent flyers may wish to consider investing in the monthly package for €15.
The service will replace the Kubi Wireless currently on offer that provides free Wi-Fi for up to 45 minutes.
