Airport is an online travel and aviation information service designed to help travelers plan trips and compare options. Its website combines a searchable directory of airports and airlines around the world with tools for finding and comparing airfares from airlines and ticket agencies. Users can search for flights by departure and arrival city, travel dates, passenger numbers, and cabin class, with a focus on finding affordable and convenient tickets.

Beyond flights, the service provides access to hotel bookings, airport transfers, car rentals, travel insurance comparisons, business lounge access, and rail tickets. Its airport reference section includes country-based listings and details such as airport names and IATA and ICAO codes, while additional resources cover airlines, aircraft, airport statuses, travel articles, and news. Travelers can also explore airport sub-sites and discount bots, and arrange paid early check-in where available. Airport describes its project as informational, with data gathered from open and official sources. Prices are provided for reference and are not a public offer.
