Airline reliability report
Tam Linhas Aereas reliability report
CAA punctuality and operations figures for Tam Linhas Aereas, covering Jan 2025 to Mar 2025.
Insufficient public data
Labels compare airlines on the same rolling window; they never predict an individual flight.
How we work this out
Each airline's rolling 12-month on-time percentage (departures early to 15 minutes late, matched flights only) is ranked against all airlines reporting at UK airports over the same window. The top third is labelled Usually reliable, the middle third Mixed reliability, and the bottom third Higher disruption risk. Airlines 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 45 airlines.
