YX 5691 earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 11 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.

Schedule

When YX 5691 flies

YX 5691 flies CMH to LGA without a single fixed slot. Its most common scheduled departure was 08:00, used on 132 of 365 flights, with 08:10 (51 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 5691 runs level with that at 85.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

YX 5691 quarter by quarter

YX 5691 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.3% on time and its weakest Oct–Dec 2025 at 75.6%, a swing of 18 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202592 flights93.3%
Oct–Dec 202592 flights75.6%
Jan–Mar 202690 flights83.8%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, YX 5691 ranged from 82.4% on Friday to 90.0% on Wednesday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 5691 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 3,624 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.

Carrier
62%
National Airspace System
29%
Extreme weather
7%
Late-arriving aircraft
3%

The largest share of delay minutes, 62%, 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 2,233 of the 3,624 delay minutes reported here. The split is drawn from 3,624 delay minutes reported on YX 5691.

Cancellations run at 3.84%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

7.1% 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.

Every one of the 365 flights under YX 5691 in the data flew CMH to LGA. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 365 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 YX 5691

For a booking, the cancellation rate is the figure to plan around on YX 5691: 3.84% of its 365 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
