Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on MCO to BWI lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 538 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 3,584 at 76.8% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Frontier on MCO to BWI from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 538 flights between July 2025 and June 2026. Beyond the headline rate, 8.9% 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 MCO to BWI
Frontier flew 538 of the 4,711 flights on MCO to BWI, about 11% of it. Its 76.5% on time is about level with the route as a whole at 75.4%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Southwest at 76.8% to Spirit at 65.9%.
The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 76.8% of the time; Spirit Airlines manages 65.9%. Sample sizes sit next to every figure, because a two-point gap across 589 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 3,584 | 76.8% | 59 min | 1.84% | B |
| Frontier Airlines (this page) | 538 | 76.5% | 77 min | 1.67% | B |
| Spirit Airlines | 589 | 65.9% | 62 min | 3.23% | C− |
Spirit Airlines cancels 3.2% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
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 30 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am148 flights89.0%
- 8am–11am44 flights90.9%
- 11am–2pm99 flights76.5%
- 2pm–5pm89 flights69.3%
- 5pm–8pm141 flights61.0%
- 8pm–5am17 flights—
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 61.0% on time, against 90.9% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 148 flights scheduled in it.
Across the year
Frontier on MCO to BWI through the year
May is the best month on the calendar at 89.5% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. April was the busiest month here, with 64 flights.
Across the week, Wednesday is the strongest day at 86.5% on time and Sunday the weakest at 62.2%. 24 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 9,554 reported delay minutes.
- 30%National Airspace System
- 26%Carrier
- 22%Extreme weather
- 22%Late-arriving aircraft
Extreme weather accounts for 22% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.6 times the usual weather exposure. The split is drawn from 9,554 reported delay minutes.
Cancellations sit at 1.67% against a national 1.81%, which is ordinary. Diversions add another 0.19%.
Connections and stage length
What a delay here costs
8.9% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 787 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 73.1% on time across 539 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 538 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 BWI
Put together: treat all of this as provisional. 538 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 76.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 528 completed flights over 12 months sit behind that.
