Airlines are responding by adding new-fangled entertainment systems and wireless internet access. But, that isn’t enough. Passengers don’t want to pay an arm and a leg for it. Luckily, there are some airlines that connectivity is a modern-day necessity, not a luxury, and they provide free Internet to help pass the time. Hop aboard one of these airlines to take advantage of it and remain productive inflight.
