Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5630, 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 5630 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 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 314 flights, with a median arrival 12 minutes early.
Set against the rest of the country, YX 5630's record is 10 points better than the US average of 77.6%. That gap is worth roughly 102 fewer late arrivals for every thousand flights.

These figures cover 314 flights between July 2025 and June 2026. The median arrival is 12 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 5630 flies
YX 5630 flies BOS to CLT without a single fixed slot. Its most common scheduled departure was 11:10, used on 60 of 314 flights, with 14:25 (49 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 11:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 5630 runs 9 points better at 87.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
YX 5630 quarter by quarter
YX 5630 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.6% on time and its weakest Jan–Mar 2026 at 81.6%, a swing of 11 points on roughly 79 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
- Jul–Sep 202579 flights89.6%
- Oct–Dec 202570 flights87.1%
- Jan–Mar 202684 flights81.6%
- Apr–Jun 202681 flights92.6%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, YX 5630 did best on Saturday at 94.6% on time and worst on Thursday at 80.4%. 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 5630 runs late
One category carries most of the weight here. Carrier accounts for 56% of the 2,401 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.
- 56%Carrier
- 29%Late-arriving aircraft
- 13%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 56%, 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 1,349 of the 2,401 delay minutes reported here. The split is drawn from 2,401 delay minutes reported on YX 5630.
Cancellations run at 3.18%, 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 4.3% 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 (244), DCA to MIA (16) and MIA to DCA (16), but none flew often enough under YX 5630 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. 314 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 5630
For a booking, the cancellation rate is the figure to plan around on YX 5630: 3.18% of its 314 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
