These figures cover 308 flights between July 2025 and June 2026. The median arrival is 15 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 F9 1733 flies

F9 1733 flies MCO to DEN without a single fixed slot. Its most common scheduled departure was 06:00, used on 225 of 308 flights. 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 1733 runs level with that at 89.9%. 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

F9 1733 quarter by quarter

F9 1733 did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.3% on time and its weakest Jul–Sep 2025 at 85.3%, a swing of 12 points on roughly 77 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, F9 1733 did best on Friday at 98.0% on time and worst on Saturday at 80.0%. Each day rests on about 44 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 1733 runs late

One category carries most of the weight here. Carrier accounts for 64% of the 1,579 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.

National Airspace System
27%
Extreme weather
6%
Late-arriving aircraft
4%

The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,005 of the 1,579 delay minutes reported here. The split is drawn from 1,579 delay minutes reported on F9 1733.

Cancellations are rare at 0.32%, 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 3.3% 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.

At 1,547 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 308 flights under F9 1733 in the data flew MCO to DEN. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 308 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 F9 1733

For a booking, F9 1733 has one of the better records a US domestic flight can show: 89.9% on time and 0.32% cancelled. That is a base rate, not a promise about any single day.
