The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Given as a target, not a fixed date, per the pin description: "…120 million passengers a year by 2030. Estimated date.…"
Airport Technology confirms King Salman International Airport has an "Expected Opening" of 2030, handling "up to 120 million travellers," matching the pin's stored 2030 date and description.
Aerotime similarly reports the airport is "expected to open by 2030" with six runways handling 120 million passengers annually, matching the pin's stored date and description.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
