AirlineQ (FlightQ)

AirlineQ is a FlightQ daily where the answer is an airport rather than a flight. The first clue is a marquee airline that operates there, with the number of flights: sometimes that settles it, like Singapore Airlines or Emirates, sometimes it is wide open, like Allegiant Air or United at a US hub.

You type a city, country, IATA or ICAO code, and the search covers every commercial airport in the world. A wrong guess shows the distance and compass direction to the answer and unlocks the next of five clue rows, so a guess of Dubai that comes back several hundred kilometres north-west points you to Doha. Most regular players land it in three or four.

Two modes go live every day: US, drawn from American hubs such as JFK, ATL, ORD and SEA and dozens more, and World, from gateways such as LHR, CDG, DXB, HND and GRU. Each has its own streak. Every daily is free with no account. The free game shows ads beside the board; a FlightQ Premium subscription removes them and adds the past-puzzles archive, unlimited practice and more stats. A free account adds groups, leaderboards and a travel passport across the FlightQ games.
