Airport reliability report
Southampton Airport reliability report
CAA punctuality and traffic figures for Southampton, covering Jan 2025 to Mar 2025.
Higher disruption risk
Labels compare airports on the same rolling window; they never predict an individual flight.
How we work this out
Each airport's rolling 12-month on-time percentage (departures early to 15 minutes late, matched flights only) is ranked against all UK reporting airports over the same window. The top third is labelled Usually reliable, the middle third Mixed reliability, and the bottom third Higher disruption risk. Airports with fewer than 1,000 matched flights in the window, or too few peers to compare, show Insufficient public data instead of a label. This comparison used 22 airports.
