tidtillflyg

Tidtillflyg is a term used in Swedish aviation planning and travel logistics to describe the amount of time available from a defined start of the journey until an aircraft’s scheduled departure. The word is a compound of tid (time), till (to) and flyg (flight); some sources write it as tidtillflyg, others break it into separate words in context.

In practice, tidtillflyg encompasses the door-to-departure interval that a traveler must clear before boarding, including travel to the airport, parking or transit, check-in, bag drop, security control and boarding procedures. It can be measured from different starting points, such as the moment a passenger leaves home, arrives at the airport, or receives their boarding pass. Metrics may distinguish between domestic and international flights, and may include or exclude transfer times at the airport.

For travelers, tidtillflyg informs planning and risk management. Shorter tidtillflyg windows increase the risk of missing a flight, while longer windows can reduce stress and allow buffers for contingencies. In travel apps and airline websites, tidtillflyg is sometimes presented as recommended arrival times at the airport.

In industry use, tidtillflyg serves as a planning and optimization metric. Airports, airlines and ground-handling providers use related concepts such as door-to-gate time and turn-around time to allocate staff, schedule security lanes, and price services. The metric is sensitive to factors such as airport size, time of day, security rules, weather, and peak-season congestion.
