These figures cover 365 flights between July 2025 and June 2026. The median arrival is 11 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 2273 flies

UA 2273 flies DEN to MSY without a single fixed slot. Its most common scheduled departure was 09:46, used on 82 of 365 flights, with 09:50 (79 flights) and 09:40 (67 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 09:46 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 2273 runs 4 points better at 87.9%. 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 2273 next to DEN to MSY

Across the year

UA 2273 quarter by quarter

Quarter by quarter UA 2273 held fairly steady: 87.0% in Jul–Sep 2025, 89.1% in Oct–Dec 2025, 85.6% in Jan–Mar 2026 and 90.1% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights87.0%
Oct–Dec 202592 flights89.1%
Jan–Mar 202690 flights85.6%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2273 ranged from 82.7% on Saturday to 90.6% on Tuesday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 2273 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 1,461 reported delay minutes.

Late-arriving aircraft
34%
Carrier
33%
National Airspace System
31%
Extreme weather
2%

No single cause dominates. late-arriving aircraft at 34%, carrier at 33% and national airspace system at 31% split the 1,461 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 1,461 delay minutes reported on UA 2273.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 1.1% 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 1,062 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 one other city pair in the data, including MSY to IAH (16), but none flew often enough under UA 2273 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to MSY only.

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.

What to do with this

Booking UA 2273

For a booking, UA 2273 has one of the better records a US domestic flight can show: 87.9% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
