Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5789, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

YX 5789 lands a B, 5 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 about 50 minutes on average. That is a workable record, not a spotless one. That rests on 301 flights, with a median arrival 8 minutes early.

Set against the rest of the country, YX 5789's record is 5 points better than the US average of 77.6%. That gap is worth roughly 45 fewer late arrivals for every thousand flights.

These figures cover 301 flights between July 2025 and June 2026. The median arrival is 8 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 5789 flies

YX 5789 flies BOS to CVG without a single fixed slot. Its most common scheduled departure was 14:35, used on 72 of 301 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 14:35 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 5789 runs 10 points better at 82.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 5789 quarter by quarter

By weekday, YX 5789 did best on Tuesday at 91.8% on time and worst on Monday at 73.9%. Each day rests on about 43 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5789 runs late

One category carries most of the weight here. Carrier accounts for 43% of the 2,625 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.

Late-arriving aircraft
27%
National Airspace System
25%
Extreme weather
5%

The largest share of delay minutes, 43%, 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 1,117 of the 2,625 delay minutes reported here. The split is drawn from 2,625 delay minutes reported on YX 5789.

Cancellations sit at 1.33% against a national 1.81%, which is ordinary. Diversions add another 0.33%.

Connections and routes

What a delay on this flight costs

5.4% 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 about 50 minutes, which a normal layover absorbs.

The 752 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.

YX 5789 is not only a BOS to CVG flight. It also flew CVG to BOS (288 flights, 65.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 301 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.
