These figures cover 327 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 UA 2636 flies

UA 2636 flies CLE to MCO without a single fixed slot. Its most common scheduled departure was 08:00, used on 123 of 327 flights, with 07:05 (63 flights) and 08:15 (50 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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 2636 runs 8 points better at 92.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 2636 next to CLE to MCO

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 82 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.

Jan–Mar 202678 flights92.3%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2636 ranged from 90.4% on Saturday to 93.6% on Wednesday. With about 47 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

One category carries most of the weight here. Carrier accounts for 44% of the 1,904 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
44%
National Airspace System
21%
Late-arriving aircraft
18%
Extreme weather
16%

Extreme weather accounts for 16% 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 2.6 times the usual weather exposure. The split is drawn from 1,904 delay minutes reported on UA 2636.

Cancellations are rare at 0.31%, below the national 1.81% 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 3.4% 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 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. 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 three other city pairs in the data, including RSW to DEN (4), DEN to ONT (4) and PHX to LAX (1), 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. 327 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: 92.0% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
