Gate Guru, a mobile resource for worldwide airports and flight information, has been acquired by TripAdvisor.
The app uses a mix of user-generated content and information from airports.
It enables travellers to view detailed maps and insights on stores, restaurants, amenities and airport gate locations.
Weather forecasts, estimated security wait times and real-time flight time information is included.
The GateGuru team will continue to operate from New York City and report to Bryan Saltzburg, general manager new initiatives and leader of the TripAdvisor flights product and SeatGuru brand.
Terms of the acquisition will not be disclosed, TripAdvisor said.
Co-founder and chief executive Steve Kaufer said: "Flying is often an essential part of a trip and we have continually developed our suite of flights products, from the pricing and availability search on TripAdvisor, to our award-winning SeatGuru.com, with seat maps and more.
"GateGuru nicely complements our existing flights products and we look forward to working with the GateGuru team as they continue to manage the GateGuru app and add great functionality to the TripAdvisor mobile experience."
