SkyWest on SYR to DTW lands a B+, level with the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 355 flights, with a median arrival 12 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on SYR to DTW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Departure window

When SkyWest runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against half a point between the best and worst carrier.

8am–11am98 flights88.8%
11am–2pm158 flights70.5%

5pm–8pm99 flights74.7%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 70.5% on time against 88.8% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 158 flights scheduled in it.

SkyWest on SYR to DTW did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.1% on time and its weakest Jan–Mar 2026 at 62.1%, a swing of 29 points on roughly 118 flights a quarter.

Delay causes

Why SkyWest runs late on this route

Carrier accounts for 64% of the 7,194 delay minutes carriers reported here, and the remaining four split what is left.

Extreme weather accounts for 25% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.1 times the usual weather exposure. The split is drawn from 7,194 reported delay minutes.

The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,604 of the 7,194 delay minutes reported here.

Cancellations are rare at 0.28%, below the national 1.89% 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 stage length

What a delay here costs

10.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 374 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.

The return leg runs 74.9% on time across 355 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 355 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 SkyWest on SYR to DTW

Put together: treat all of this as provisional. 355 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 76.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 353 completed flights over 12 months sit behind that.
