Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.

SkyWest on BNA to LGA lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 178 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 1,696 at 72.5% on time.

Set against the rest of the country, SkyWest's BNA to LGA record is 6 points better than the US average of 77.6%. That gap is worth roughly 60 fewer late arrivals for every thousand flights.

Every carrier on BNA to LGA, 3,805 flights

These figures cover 178 flights between July 2025 and June 2026. The median arrival is 13 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

SkyWest against every carrier on BNA to LGA

SkyWest flew 178 of the 3,805 flights on BNA to LGA, about 5% of it. Its 83.6% on time is 12 points better than the route as a whole, which runs 71.8%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from SkyWest at 83.6% to American at 60.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The three carriers here are closely matched: 4 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Delta Air Lines cancels 4.9% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window

When SkyWest runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 178 flights.

There are not enough flights in each departure window to split SkyWest's BNA to LGA record by time of day without the percentages moving on noise. The headline rate of 83.6% is the reliable figure here.

Across the year

SkyWest on BNA to LGA through the year

Jul–Sep 202598 flights87.8%
Oct–Dec 202580 flights78.5%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 83.6% on time across 178 flights.

Split by quarter, SkyWest on BNA to LGA logged 98 flights in Jul–Sep 2025 and 80 flights in Oct–Dec 2025. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 83.6% annual figure is the one to use.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 86% of the 2,287 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

86%
National Airspace System

Extreme weather
5%

The largest share of delay minutes, 86%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,965 of the 2,287 delay minutes reported here. The split is drawn from 2,287 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

6.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The 764 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 61.3% on time across 178 flights, 22 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 22 points of difference.

One caution: this is a thin sample. 178 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking SkyWest on BNA to LGA

Put together: treat all of this as provisional. 178 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 83.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 177 completed flights over 12 months sit behind that.
