Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Southwest Airlines.

Southwest on MCO to PHX 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 about 55 minutes on average. That rests on 841 flights, with a median arrival 3 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate Southwest on MCO to PHX from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 841 flights between September 2025 and August 2026. The median arrival is 3 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.

Carrier by carrier

Southwest against every carrier on MCO to PHX

Southwest flew 841 of the 1,844 flights on MCO to PHX, about 46% of it. Its 78.9% on time is about level with the route as a whole at 78.9%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Frontier at 82.9% to American at 78.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When Southwest runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 28 points, against half a point between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.1% of the time, against 65.0% for the evening window. That is 28 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 274 flights scheduled in it.

Delay causes

Why Southwest runs late on this route

Late-arriving aircraft accounts for 44% of the 9,558 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    44%
  • Carrier
    29%
  • National Airspace System
    17%
  • Extreme weather
    10%
  • Security
    1%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,558 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 9,558 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 93.1% on time here.

Cancellations are rare at 0.36%, 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 costs

6.1% 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 about 55 minutes, which a normal layover absorbs.

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 runs 76.5% on time across 857 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. 841 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 Southwest on MCO to PHX

Put together: treat all of this as provisional. 841 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 78.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 837 completed flights over 12 months sit behind that.
