Frontier on RDU to MCO sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 724 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,005 at 81.9% on time.

The national on-time rate over the same period is 77.6%, so Frontier on RDU to MCO runs 5 points behind the country as a whole. Across a thousand flights that is about 46 extra late arrivals.

These figures cover 724 flights between July 2025 and June 2026. Beyond the headline rate, 12.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Frontier against every carrier on RDU to MCO

Frontier flew 724 of the 2,702 flights on RDU to MCO, about 27% of it. Its 73.0% on time is 5 points worse than the route as a whole, which runs 78.3%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Delta at 81.9% to Frontier at 73.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 4 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Departure window

When Frontier runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 4 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am51 flights90.0%
  • 8am–11am76 flights80.0%
  • 11am–2pm137 flights73.9%
  • 2pm–5pm146 flights68.3%
  • 5pm–8pm92 flights79.3%
  • 8pm–5am222 flights66.5%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.0% of the time, against 66.5% for the overnight window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 222 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.October best, December worst

December is the weak month at 49.0% on time, against 86.3% in October. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 79 flights.

Across the week, Thursday is the strongest day at 80.3% on time and Sunday the weakest at 59.6%. 21 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Frontier runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 18,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Late-arriving aircraft
    62%
  • Carrier
    22%
  • National Airspace System
    15%
  • Extreme weather
    0%

62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 18,000 reported delay minutes here, that single category outweighs weather by 62 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 17,804 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 90.0% on time here.

Cancellations sit at 1.80% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 534 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 78.4% on time across 724 flights, 5 points above 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 5 points of difference.

One caution: this is a thin sample. 724 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 RDU to MCO

Put together: treat all of this as provisional. 724 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 73.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 711 completed flights over 12 months sit behind that.
