YX 5671 sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 312 flights, with a median arrival 8 minutes early.

These figures cover 312 flights between July 2025 and June 2026. Beyond the headline rate, 13.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When YX 5671 flies

YX 5671 flies LGA to CMH without a single fixed slot. Its most common scheduled departure was 17:30, used on 202 of 312 flights. 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 17:30 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and YX 5671 runs 6 points better at 74.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

YX 5671 quarter by quarter

Quarter by quarter YX 5671 held fairly steady: 79.2% in Jul–Sep 2025, 69.7% in Oct–Dec 2025, 70.6% in Jan–Mar 2026 and 77.3% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202582 flights79.2%

By weekday, YX 5671 did best on Wednesday at 83.0% on time and worst on Sunday at 69.6%. Each day rests on about 45 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5671 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,073 reported delay minutes.

Late-arriving aircraft
41%
National Airspace System
31%
Carrier
27%
Extreme weather
2%

41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,073 reported delay minutes here, that single category outweighs weather by 21 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,073 delay minutes reported on YX 5671.

Cancellations run at 5.13%, against 1.81% nationally. That is about one flight in twenty 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on two other city pairs in the data, including DTW to MEM (11) and ORD to JFK (1), but none flew often enough under YX 5671 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to CMH only.

One caution: this is a thin sample. 312 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 5671

For a booking, the cancellation rate is the figure to plan around on YX 5671: 5.13% of its 312 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.
