Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2463, check with United Airlines.
UA 2463 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 365 flights, with a median arrival 1 minute early.
The national on-time rate over the same period is 77.6%, so UA 2463 runs 8 points behind the country as a whole. Across a thousand flights that is about 77 extra late arrivals.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 11.3% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 2463 flies
UA 2463 flies IAD to MCO without a single fixed slot. Its most common scheduled departure was 17:15, used on 88 of 365 flights, with 17:50 (56 flights) and 17:25 (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 17:15 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2463 runs level with that at 69.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
UA 2463 next to IAD to MCO

Across the year
UA 2463 quarter by quarter
UA 2463 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.3% on time and its weakest Jul–Sep 2025 at 50.0%, a swing of 31 points on roughly 91 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 2463 did best on Tuesday at 84.9% on time and worst on Sunday at 54.0%. Each day rests on about 52 flights, so a gap of 31 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2463 runs late
One category carries most of the weight here. National Airspace System accounts for 61% of the 8,344 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.
- 61%National Airspace System
- 21%Late-arriving aircraft
- 11%Carrier
- 7%Extreme weather
61% 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 5,074 minutes out of 8,344, against a national NAS share of 21%. The split is drawn from 8,344 delay minutes reported on UA 2463.
Cancellations are rare at 0.55%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.3% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 758 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.
UA 2463 is not only a IAD to MCO flight. It also flew RDU to IAD (261 flights, 74.7% 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. 365 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.
