6. SeatGuru by TripAdvisor (free)
To help make travel as pleasant as possible, TripAdvisor developed this nifty app to give you details about seats before you select them. Among other features, it lets users access more than 700 seat maps from approximately 100 airlines, and gives information to travelers drawn from other customers’ reviews and insights — whether the seat has a personal T.V. or has a likelihood of getting bumped on passengers’ way to the toilet, for example. It also allows you to find and compare low airfares from major airlines, low-cost carriers, and travel agents.
