These figures cover 359 flights between September 2025 and August 2026. The median arrival is 14 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.

Delay causes

Why DL 775 runs late

Carrier accounts for 44% of the 2,816 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
44%
Late-arriving aircraft
42%
National Airspace System
14%
Extreme weather
1%

42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,816 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 2,816 delay minutes reported on DL 775.

Cancellations run at 2.51%, against 1.89% nationally. That is about one flight in 40 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 4.0% 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 554 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.

DL 775 is not only a CLE to ATL flight. It also flew ATL to CLE (359 flights, 85.7% 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. 359 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 DL 775
