Live departure crowding at Oslo Gardermoen Airport. Each bar is one departure, drawn from the moment passengers turn up until boarding closes. Where bars stack, the terminal is full.
The load curve is relative, not a headcount: every flight is weighted equally, so 100% is simply the busiest minute of the day shown. A day of small propliners and a day of full charters look the same — what the curve tells you is when the building fills up, not by how much. Times are shown in the airport's own timezone. Data refreshes every 5 minutes.
Airport departure boards tell you when flights leave, but not how crowded the building will be. This page draws every departing flight as a bar spanning the time its passengers are inside the terminal — from arrival (default 3 hours before departure) until boarding closes — and sums the overlaps into a per-minute relative load curve. The peak of that curve is the moment to avoid, or to aim for if you like queues short.
