These figures cover 283 flights between September 2025 and August 2026. The median arrival is 16 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 06:25 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 5626 runs level with that at 89.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why YX 5626 runs late

Carrier accounts for 46% of the 1,571 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
46%
National Airspace System
43%
Extreme weather
6%
Late-arriving aircraft
5%

43% 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 674 minutes out of 1,571, against a national NAS share of 21%. The split is drawn from 1,571 delay minutes reported on YX 5626.

Cancellations run at 3.89%, against 1.89% nationally. That is about one flight in 25 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 2.6% land an hour or more behind schedule, against 8.3% 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.

The same number turns up on three other city pairs in the data, including CLT to BOS (246), LGA to MEM (26) and JAX to BOS (5), 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. 283 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: 3.89% of its 283 scheduled flights did not operate. A late arrival costs about 55 minutes, but a cancellation costs the day, so leave a later option open.
