This route 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 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 1,457 SLC to BUR flights, of which SkyWest Airlines flew 939 at 90.9% on time.
Best time to fly SLC to BUR: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 96.2% of the time and Tuesday flights 93.0%, against 87.5% 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 102 fewer late arrivals for every thousand flights.

These figures cover 1,457 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 BUR
The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 90.9% of the time; Delta Air Lines manages 82.4%. Sample sizes sit next to every figure, because a two-point gap across 423 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| SkyWest Airlines | 939 | 90.9% | 60 min | 0.53% | A+ |
| Delta Air Lines | 423 | 82.4% | 62 min | 0.00% | B+ |
| Southwest Airlinesthin sample | 95 | 76.3% | 53 min | 1.05% | B |
SkyWest leads Delta by 9 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

The most reliable ways to fly Salt Lake City to Burbank
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 4 of the top 5 use a different airport at one end.

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.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 9 points between the best and worst carrier.
- 5am–8am55 flights96.2%
- 8am–11am467 flights91.5%
- 11am–2pm177 flights75.9%

- 5pm–8pm3 flights—
- 8pm–5am364 flights82.3%
Scale runs 65% to 100%. 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 75.9% on time against 96.2% for 5am–8am. 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 8am–11am window is the busiest, with 467 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 14 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.
Delays peak in October, when the on-time rate falls to 80.3%. June is the strongest month at 94.1%. Moving a flexible trip across that boundary buys 14 points. October was the busiest month here, with 138 flights.
Across the week, Tuesday is the strongest day at 93.0% on time and Thursday the weakest at 82.2%, a spread of 11 points.
Delay causes
Why this route gets delayed
Carrier accounts for 68% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 68%Carrier
- 19%Late-arriving aircraft
- 8%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 68%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,278 of the 11,000 delay minutes reported here. The split is drawn from 10,766 reported delay minutes.
Cancellations are rare at 0.41%, 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
Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% 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 574 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.
The return leg is a different operation and performs like one: it runs 90.8% on time across 1,457 flights, 3 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 3 points of difference.
The sample behind these figures is 1,457 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. June runs 94.1% on time and October 80.3%, a swing of 14 points. If the dates move at all, move them out of October before you think about anything else. 1,442 completed flights over 12 months sit behind that.
Common questions
SLC to BUR questions
How often is SLC to BUR 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 12.5% of the 1,457 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 BUR?
SkyWest Airlines leads at 90.9% on time across 939 flights. Delta Air Lines is at the other end on 82.4%, a gap of 9 points. 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 BUR?
The 5am–8am departure window is the strongest at 96.2% on time. The 11am–2pm window is the weakest at 75.9%, 20 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 October delays on SLC to BUR?
October is the weakest month at 80.3% on time, compared with 94.1% in June. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
