A check mark and green mark the better figure in a row (higher for on-time rates, lower for delays and cancellations) when the gap is larger than chance would produce: a two-proportion test on each side’s flight count, at about 95% confidence. “Too close to call” rows differ by less than that. Average and median delay carry no sample-error estimate here, so they are marked by the printed figure alone.
EWR → SAN (Newark to San Diego · 2,425 mi): July 2023 – July 2026. FlyerIntel keeps one total per airline for the route, not the dates each airline started or stopped flying it, so an airline that flew the route for only part of that time is measured over that part.

Month by month
There is no month-by-month chart for these airlines. FlyerIntel keeps monthly figures for each route and for each airline across its whole network, but not for one airline on one route. The EWR → SAN route page shows the route’s own trend.
