These figures cover 3,511 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.8% of the time, against 73.8% for the evening window. That is 17 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 713 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.February best, November worst

Delays peak in November, when the on-time rate falls to 78.7%. February is the strongest month at 88.3%. Moving a flexible trip across that boundary buys 10 points. March was the busiest month here, with 360 flights.

Across the week, Wednesday is the strongest day at 88.3% on time and Monday the weakest at 78.5%, a spread of 10 points.

Delay causes

Why this route gets delayed

Carrier accounts for 42% of the 48,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    42%
  • Late-arriving aircraft
    39%
  • National Airspace System
    11%
  • Extreme weather
    7%
  • Security
    0%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 48,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 47,815 reported delay minutes.

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 20,000 of the 48,000 delay minutes reported here.

Cancellations are rare at 0.51%, 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

7.1% 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 109 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 5am–8am window matters as much as it does.

The return leg runs 81.0% on time across 3,508 flights, within 3 points 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 3,511 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.

Booking this route

Put together: avoid the 5pm–8pm departure. It runs 73.8% on time against 90.8% for the 5am–8am slot, and that 17 points is the largest single thing you control here. American Airlines is the strongest operator if the fares are close. 3,491 completed flights over 12 months sit behind that.

Common questions

TUS to PHX questions

How often is TUS to PHX delayed?

About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 16.4% of the 3,511 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.

Which airline is most reliable on TUS to PHX?

American Airlines leads at 87.8% on time across 365 flights. SkyWest Airlines is at the other end on 82.6%, a gap of 5 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 TUS to PHX?

The 5am–8am departure window is the strongest at 90.8% on time. The 5pm–8pm window is the weakest at 73.8%, 17 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 November delays on TUS to PHX?

November is the weakest month at 78.7% on time, compared with 88.3% in February. Across the year that is 10 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
