This route 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 988 DRO to PHX flights, with a median arrival 7 minutes early.
Best time to fly DRO to PHX: a 2pm–5pm departure, ideally on a Wednesday. Flights in that window arrived on time 96.9% of the time and Wednesday flights 79.8%, against 76.7% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Across the year
When delays peak on this route
This route's year swings by 18 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 68.9% on time, 18 points below January, the best at 87.3%. 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. March was the busiest month here, with 91 flights.
Across the week, Wednesday is the strongest day at 79.8% on time and Thursday the weakest at 68.9%, a spread of 11 points.
Delay causes
Why this route gets delayed
Carrier accounts for 63% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Carrier
- 26%Late-arriving aircraft
- 7%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 63%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 19,000 delay minutes reported here. The split is drawn from 19,302 reported delay minutes.
Cancellations are rare at 0.40%, 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
8.1% 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 an hour and a half, which a normal layover absorbs.
At 352 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 2pm–5pm window matters as much as it does.
The return leg runs 78.8% on time across 987 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. 988 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 this route
Put together: treat all of this as provisional. 988 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 76.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 982 completed flights over 12 months sit behind that.
Common questions
DRO to PHX questions
How often is DRO to PHX delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.3% of the 988 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is DRO to PHX compared with the rest of the country?
76.7% of flights arrive on time here against a national 77.3%, a difference of half a point against it. That is worth a B+ on this site's grading scale.
What time of day has the fewest delays on DRO to PHX?
The 2pm–5pm departure window is the strongest at 96.9% on time. The 5pm–8pm window is the weakest at 63.2%, 34 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 DRO to PHX?
July is the weakest month at 68.9% on time, compared with 87.3% in January. Across the year that is 18 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
