These figures cover 333 flights between September 2025 and August 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.

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

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 2636 runs 9 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

UA 2636 quarter by quarter

UA 2636 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.6% on time and its weakest Oct–Dec 2025 at 85.7%, a swing of 11 points on roughly 83 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.

By weekday, UA 2636 ranged from 90.4% on Monday to 93.6% on Wednesday. With about 48 flights behind each day, a spread of 3 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 2636 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,770 reported delay minutes.

Carrier
42%
Late-arriving aircraft
20%
National Airspace System
20%
Extreme weather
18%

Extreme weather accounts for 18% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.9 times the usual weather exposure. The split is drawn from 1,770 delay minutes reported on UA 2636.

Cancellations are rare at 0.30%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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 8.3% 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 895 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 two other city pairs in the data, including RSW to DEN (4) and DEN to ONT (4), but none flew often enough under UA 2636 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CLE to MCO only.

One caution: this is a thin sample. 333 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 UA 2636

For a booking, UA 2636 has one of the better records a US domestic flight can show: 92.5% on time and 0.30% cancelled. That is a base rate, not a promise about any single day.
