These figures cover 207 flights between September 2025 and August 2026. The median arrival is 14 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.

Departure window

When Frontier runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 207 flights.

  • 5am–8am—
  • 8am–11am89 flights86.5%
  • 11am–2pm21 flights—
  • 2pm–5pm11 flights—
  • 5pm–8pm13 flights—
  • 8pm–5am73 flights78.9%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 86.5% on time for the 8am–11am window against 78.9% for 8pm–5am. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am window is the busiest, with 89 flights scheduled in it.

Delay causes

Why Frontier runs late on this route

Carrier accounts for 43% of the 1,530 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    43%
  • Late-arriving aircraft
    38%
  • National Airspace System
    17%
  • Extreme weather
    2%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,530 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 1,530 reported delay minutes.

The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 654 of the 1,530 delay minutes reported here.

Cancellations sit at 0.97% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 8.3% 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.

At 1,849 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 is a different operation and performs like one: it runs 74.6% on time across 208 flights, 8 points below 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 8 points of difference.

One caution: this is a thin sample. 207 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 MCO to PHX

Put together: treat all of this as provisional. 207 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 82.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 205 completed flights over 12 months sit behind that.
