A recent survey of airline passengers has stated that Wi-Fi was more important than food for the passengers traveling by air. This shows how connected people are to the internet. And even the airlines are trying to retain existing customers and attract more customers by providing entertainment and connectivity to them.
Many airlines already are offering Wi-Fi in at least some of their flights, but the travelers have to buy the service. Airlines provide free internet access only to the travelers in first class. Big names in the aviation planning like Etihad, Lufthansa, etc. provide internet access on all or some of its fleet, but at a cost to the passenger.
