Frontier on CLE to PHX lands a B, level with the national rate of 77.3%. Roughly 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 327 flights, with a median arrival 7 minutes early.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 48% of the 6,245 delay minutes carriers reported here, and the remaining four split what is left.

48%

National Airspace System

Extreme weather
1%

48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,245 reported delay minutes here, that single category outweighs weather by 39 to one. The split is drawn from 6,245 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 87.7% on time here.

Cancellations sit at 2.14% against a national 1.89%, which is ordinary. Diversions add another 1.53%.

Connections and stage length

What a delay here costs

10.8% 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 1,737 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg runs 76.2% on time across 328 flights, within about a point 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. 327 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 Frontier on CLE to PHX

Put together: treat all of this as provisional. 327 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 77.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 315 completed flights over 12 months sit behind that.
