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 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 1,484 SLC to BUR flights, of which SkyWest Airlines flew 962 at 89.5% 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 90.1%, against 86.0% for the route overall.
Set against the rest of the country, this route's record is 8 points better than the US average of 77.6%. That gap is worth roughly 84 fewer late arrivals for every thousand flights.

89.5% on time across 962 flights
These figures cover 1,484 flights between July 2025 and June 2026. The median arrival is 8 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 89.5% of the time; Delta Air Lines manages 81.6%. Sample sizes sit next to every figure, because a two-point gap across 394 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| SkyWest Airlines | 962 | 89.5% | 51 min | 0.52% | A+ |
| Delta Air Lines | 394 | 81.6% | 98 min | 0.00% | B+ |
| Southwest Airlinesthin sample | 128 | 73.0% | 49 min | 0.78% | C+ |
SkyWest leads Delta by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Best ways to make this trip
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 23 points, against 8 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am55 flights96.2%
- 8am–11am400 flights92.4%
- 11am–2pm242 flights73.6%
- 2pm–5pm416 flights89.2%
- 5pm–8pm8 flights—
- 8pm–5am363 flights82.0%
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 73.6% 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 2pm–5pm window is the busiest, with 416 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 20 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.
July is the worst month at 74.6% on time, 20 points below June, the best at 94.1%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. August was the busiest month here, with 140 flights.
Across the week, Tuesday is the strongest day at 90.1% on time and Thursday the weakest at 81.9%. 8 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Carrier accounts for 69% of the 14,000 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.
- 69%Carrier
- 19%Late-arriving aircraft
- 7%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 9,481 of the 14,000 delay minutes reported here. The split is drawn from 13,782 reported delay minutes.
Cancellations are rare at 0.40%, 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 stage length
What a delay here actually costs
Badly late arrivals are rare here: only 3.9% 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 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. 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.
The return leg is a different operation and performs like one: it runs 90.9% on time across 1,484 flights, 5 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 5 points of difference.
The sample behind these figures is 1,484 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 July 74.6%, a swing of 20 points. If the dates move at all, move them out of July before you think about anything else. 1,470 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 seven arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 14.0% of the 1,484 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on SLC to BUR?
SkyWest Airlines leads at 89.5% on time across 962 flights. Delta Air Lines is at the other end on 81.6%, a gap of 8 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 73.6%, 23 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 July delays on SLC to BUR?
July is the weakest month at 74.6% on time, compared with 94.1% in June. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
