I'm planning an international trip and would like to know which airline provides the best inflight entertainment. I've heard that Qatar Airways, Emirates, British Airways, Etihad Airways, and Delta Airlines all offer excellent movie libraries, music, games, and touchscreen systems. For those who have flown with these airlines, which one delivers the best overall entertainment experience? Are there any airlines that also provide Wi-Fi, live TV, or exclusive content during the flight? I'd appreciate your recommendations.
