These figures cover 310 flights between July 2025 and June 2026. The median arrival is 9 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 4799 flies

YX 4799 flies CMH to LGA without a single fixed slot. Its most common scheduled departure was 06:00, used on 105 of 310 flights, with 06:38 (34 flights) and 06:50 (31 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 4799 runs level with that at 88.1%. 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 4799 quarter by quarter

Quarter by quarter YX 4799 held fairly steady: 91.7% in Jul–Sep 2025, 88.0% in Oct–Dec 2025, 83.3% in Jan–Mar 2026 and 89.2% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202573 flights91.7%

By weekday, YX 4799 did best on Saturday at 93.5% on time and worst on Friday at 80.0%. Each day rests on about 44 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4799 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 2,070 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.

The largest share of delay minutes, 55%, 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 1,137 of the 2,070 delay minutes reported here. The split is drawn from 2,070 delay minutes reported on YX 4799.

Cancellations sit at 2.26% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

Every one of the 310 flights under YX 4799 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. 310 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 4799
