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.
Airlines on LGA → BOS
Every airline with at least 200 flights on this route, over the route's reporting period.
No side is clearly ahead of the rest on any of the 4 rates measured; the best figures are too close to call: Republic Airways, JetBlue, and American Airlines on 2, JetBlue and American Airlines on 1, Delta Air Lines and American Airlines on 1.
| Metric | Republic Airways | JetBlue | Delta Air Lines | American Airlines |
|---|---|---|---|---|
| On-time arrival · too close to call | 78.8% | 80.3% (best, but too close to call) | 73.7% | 79.5% (too close to call with the best) |
| Cancellation rate · too close to call | 4.07% | 3.22% | 2.21% (too close to call with the best) | 1.54% (best, but too close to call) |
| Severe delay (60+ min) · too close to call | 8.8% (best, but too close to call) | 9.4% (too close to call with the best) | 14.3% | 9.1% (too close to call with the best) |
| Average arrival delay | 4 min | 4 min | 15 min | 5 min |
| Median arrival delay | -10 min | -15 min (best) | -9 min | -14 min |
| Departure on-time · too close to call | 80.0% (best, but too close to call) | 79.3% (too close to call with the best) | 72.7% | 78.7% (too close to call with the best) |
| Flights analyzed | 16,024 | 4,408 | 1,814 | 716 |
A check mark and green mark the best figure in a row (higher for on-time rates, lower for delays and cancellations) when it is clearly better than every other side’s: a two-proportion test against each, on that side’s flight count, at about 95% confidence. When it is not, the row says “too close to call” and a “≈” marks the sides that cannot be told apart from the best figure. Average and median delay carry no sample-error estimate here, so they are marked by the printed figure alone.
LGA → BOS (New York to Boston · 184 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 LGA → BOS route page shows the route’s own trend.
