Compare the airlines on a route

Enter a route to see every airline that flies it with enough flights, side by side on the same metrics, from the same source.

One route, as origin and destination codes joined by a hyphen, e.g. ATL-LGA. Shows the airlines with enough flights on it, up to four.

Airlines on EWR → SAT

Every airline with at least 200 flights on this route, over the route's reporting period.

No clear difference between United Airlines and Spirit Airlines on the 4 rates measured: the gaps are small enough to be chance.

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 → SAT (Newark to San Antonio · 1,569 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.

Source: FlyerIntel analysis of US DOT BTS data · Airlines with fewer than 200 flights on this route are left out.

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 → SAT route page shows the route’s own trend.
