Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5626, 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 5626 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 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 278 flights, with a median arrival 15 minutes early.

Set against the rest of the country, YX 5626's record is 12 points better than the US average of 77.6%. That gap is worth roughly 123 fewer late arrivals for every thousand flights.

These figures cover 278 flights between July 2025 and June 2026. The median arrival is 15 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 5626 flies

YX 5626 flies BOS to CLT without a single fixed slot. Its most common scheduled departure was 08:15, used on 39 of 278 flights, with 07:55 (36 flights) and 07:10 (32 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 08:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 5626 runs 6 points better at 89.9%. 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 5626 quarter by quarter

Quarter by quarter YX 5626 held fairly steady: 93.4% in Jul–Sep 2025, 90.9% in Oct–Dec 2025, 84.3% in Jan–Mar 2026 and 93.8% 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 202576 flights93.4%

By weekday, YX 5626 ranged from 87.8% on Monday to 92.5% on Tuesday. With about 40 flights behind each day, a spread of 5 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 5626 runs late

One category carries most of the weight here. Carrier accounts for 53% of the 1,392 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
53%
National Airspace System
35%
Extreme weather
7%
Late-arriving aircraft
6%

35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 486 minutes out of 1,392, against a national NAS share of 21%. The split is drawn from 1,392 delay minutes reported on YX 5626.

Cancellations run at 2.88%, against 1.81% nationally. That is roughly 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 3.0% 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 728 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.

The same number turns up on four other city pairs in the data, including CLT to BOS (241), LGA to MEM (26) and BOS to RDU (6), but none flew often enough under YX 5626 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to CLT only.

One caution: this is a thin sample. 278 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 5626

For a booking, the cancellation rate is the figure to plan around on YX 5626: 2.88% of its 278 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
