This route lands a B+, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 987 PHX to DRO flights, with a median arrival 5 minutes early.
Best time to fly PHX to DRO: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 85.4% of the time and Tuesday flights 91.1%, against 78.8% 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.

Book the morning departure. Flights leaving between 8am–11am arrive on time 85.4% of the time, against 72.3% for the overnight window. That is 13 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 363 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 16 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.
April is the best month on the calendar at 88.4% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. March was the busiest month here, with 91 flights.
Across the week, Tuesday is the strongest day at 91.1% on time and Thursday the weakest at 74.5%, a spread of 17 points.
Delay causes
Why this route gets delayed
Carrier accounts for 57% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 32%Late-arriving aircraft
- 7%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 11,000 of the 19,000 delay minutes reported here. The split is drawn from 18,524 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 85.4% on time here.
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
9.1% 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 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 8am–11am window matters as much as it does.
The return leg runs 76.7% on time across 988 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. 987 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. 987 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 78.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 983 completed flights over 12 months sit behind that.
Common questions
PHX to DRO questions
How often is PHX to DRO delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 21.2% of the 987 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is PHX to DRO compared with the rest of the country?
78.8% of flights arrive on time here against a national 77.3%, a difference of 2 points in its favour. That is worth a B+ on this site's grading scale.
What time of day has the fewest delays on PHX to DRO?
The 8am–11am departure window is the strongest at 85.4% on time. The 8pm–5am window is the weakest at 72.3%, 13 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 March delays on PHX to DRO?
March is the weakest month at 72.5% on time, compared with 88.4% in April. Across the year that is 16 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
