This route earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 1,219 SLC to JAC flights, of which Delta Air Lines flew 741 at 87.2% on time.
Best time to fly SLC to JAC: a 8pm–5am departure, ideally on a Tuesday. Flights in that window arrived on time 93.4% of the time and Tuesday flights 94.0%, against 86.8% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 1,219 flights between September 2025 and August 2026. The median arrival is 9 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.

Carrier by carrier
Which airline is most reliable on SLC to JAC
The two carriers here are closely matched: about a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 741 | 87.2% | 59 min | 0.54% | A+ |
| SkyWest Airlines | 478 | 86.1% | 71 min | 1.26% | A |
No carrier stands out. Delta tops the table at 87.2%, about a point clear of the bottom, which is inside the range this kind of sample moves year to year.

Best ways to make this trip
The most reliable ways to fly Salt Lake City to Jackson
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. SLC → JACSalt Lake City to Jackson | Delta Air Lines | 86.7% | 87.2% | 0.54% | 8pm–5am, Tue | DL 2282 11:10 |
| 2. SLC → JACSalt Lake City to Jackson | SkyWest Airlines | 85.0% | 86.1% | 1.26% | 8pm–5am, Tue | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.

Across the year
When delays peak on this route
This route's year swings by 13 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
February is the weak month at 80.0% on time, against 93.1% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 123 flights.
Across the week, Tuesday is the strongest day at 94.0% on time and Sunday the weakest at 84.4%, a spread of 10 points.
Delay causes
Why this route gets delayed
Carrier accounts for 64% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 15%Late-arriving aircraft
- 11%Extreme weather
- 11%National Airspace System
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,519 of the 10,000 delay minutes reported here. The split is drawn from 10,171 reported delay minutes.
Cancellations are rare at 0.82%, 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 actually costs
5.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 205 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 8pm–5am window matters as much as it does.
The return leg runs 86.6% on time across 1,217 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,219 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 93.1% on time and February 80.0%, a swing of 13 points. If the dates move at all, move them out of February before you think about anything else. 1,200 completed flights over 12 months sit behind that.
Common questions
SLC to JAC questions
How often is SLC to JAC delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.2% of the 1,219 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on SLC to JAC?
Delta Air Lines leads at 87.2% on time across 741 flights. SkyWest Airlines is at the other end on 86.1%, a gap of about a point. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on SLC to JAC?
The 8pm–5am departure window is the strongest at 93.4% on time. The 5pm–8pm window is the weakest at 83.6%, 10 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are February delays on SLC to JAC?
February is the weakest month at 80.0% on time, compared with 93.1% in September. Across the year that is 13 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
