Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5355, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 5355 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.2 hours. That rests on 349 flights, with a median arrival 12 minutes early.

These figures cover 349 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 OO 5355 flies

OO 5355 flies ICT to DEN without a single fixed slot. Its most common scheduled departure was 06:05, used on 138 of 349 flights, with 06:00 (110 flights) and 06:15 (96 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 06:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5355 runs 2 points better at 91.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, OO 5355 did best on Thursday at 98.0% on time and worst on Saturday at 84.1%. Each day rests on about 50 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5355 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 3,887 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
61%
Late-arriving aircraft
37%
National Airspace System
2%

37% 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 3,887 reported delay minutes here, that single category outweighs weather by 37 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 3,887 delay minutes reported on OO 5355.

Cancellations are rare at 0.57%, 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 3.5% 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 same number turns up on two other city pairs in the data, including ORD to ORF (3) and SLC to DEN (1), but none flew often enough under OO 5355 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ICT to DEN only.

One caution: this is a thin sample. 349 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 OO 5355

For a booking, OO 5355 has one of the better records a US domestic flight can show: 91.6% on time and 0.57% cancelled. That is a base rate, not a promise about any single day.
