These figures cover 329 flights between July 2025 and June 2026. Beyond the headline rate, 11.0% 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 F9 4418 flies

F9 4418 flies ELP to DEN without a single fixed slot. Its most common scheduled departure was 13:33, used on 37 of 329 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 13:33 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and F9 4418 runs level with that at 78.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

F9 4418 quarter by quarter

F9 4418 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.9% on time and its weakest Jul–Sep 2025 at 74.0%, 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.

By weekday, F9 4418 did best on Saturday at 86.5% on time and worst on Thursday at 69.2%. Each day rests on about 47 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 4418 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 6,427 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.

Extreme weather
0%

54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,427 reported delay minutes here, that single category outweighs weather by 54 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,427 delay minutes reported on F9 4418.

Cancellations are rare at 0.61%, 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. 11.0% 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 563 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.

Every one of the 329 flights under F9 4418 in the data flew ELP 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. 329 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 4418
