Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5698, 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 5698 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 15 points better than the national rate of 77.6%.

These figures cover 318 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.

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

A 06:59 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 5698 runs 3 points better at 92.5%. 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 5698 quarter by quarter

Quarter by quarter YX 5698 held fairly steady: 98.6% in Jul–Sep 2025, 91.0% in Oct–Dec 2025, 89.9% in Jan–Mar 2026 and 91.1% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202573 flights98.6%

By weekday, YX 5698 did best on Wednesday at 98.0% on time and worst on Friday at 84.0%. Each day rests on about 45 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5698 runs late

One category carries most of the weight here. Carrier accounts for 77% of the 1,546 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.

Extreme weather

The largest share of delay minutes, 77%, 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 1,197 of the 1,546 delay minutes reported here. The split is drawn from 1,546 delay minutes reported on YX 5698.

Cancellations run at 3.46%, against 1.81% nationally. That is about one flight in 30 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

Badly late arrivals are rare here: only 3.6% 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.

The same number turns up on one other city pair in the data, including CLE to LGA (12), but none flew often enough under YX 5698 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to BOS only.

One caution: this is a thin sample. 318 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 5698

For a booking, the cancellation rate is the figure to plan around on YX 5698: 3.46% of its 318 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
