Sometimes happiness is Wi-Fi or a comfy seat rather than just a cheap flight.
What it does: This website considers more than just ticket price to find you a more pleasant flight. It has computed "happiness scores" for billions of flight combinations across 4,000 airports, 750 airlines, 180 types of planes and 2,200 airline, aircraft and cabin types.
What's hot: All the added info. After your flight search result comes up — make sure to scroll over the individual visual cues such as "overall rating," "roomier" for seat pitch, "on demand" for entertainment details and "plugs" for power outlets — click the "more" button for a full page of detailed info. Airline and airport nerds can geek out in the "Tips & Reviews" section. You also can get the RouteHappy app (free) to review a flight and share photos and tips.
