What the record says about this route
Which airline you fly changes the odds here. Gol Linhas Aéreas arrived on time 8.9 points more often than Azul Linhas Aéreas over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
The two directions do not behave alike. GRU to CWB arrives on time 10.8 points less often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.
This is a thin route — 401 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.
The Curitiba to São Paulo route sits close to the middle of the record — neither notably punctual nor notably late.
Which airline should you fly on this route?

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on CWB to GRU during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
