Carrier by carrier
Frontier against every carrier on BWI to CLT
Frontier flew 163 of the 2,948 flights on BWI to CLT, about 6% of it. Its 71.4% on time is 9 points worse than the route as a whole, which runs 80.8%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from Envoy at 100.0% to Frontier at 71.4%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. American Airlines arrives on time 84.6% of the time; Southwest Airlines manages 75.5%. Sample sizes sit next to every figure, because a two-point gap across 965 flights means less than a ten-point one.

American leads Southwest by 9 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Share of 154 completed flights by arrival against schedule.
10 of 42 late departures made up the time and arrived on time, 24% of them. In the other direction, 12 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CLT.
The worst days
Worst days for Frontier on BWI to CLT
The latest arrival of the period was on 11 May 2026, 21 hours 29 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 11 May 2026 | 21 hours 29 minutes | Late-arriving aircraft |
| 18 July 2026 | 3 hours 25 minutes | National Airspace System |
| 28 July 2026 | 3 hours 8 minutes | National Airspace System |

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 57% of the 4,311 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 33%National Airspace System
- 10%Carrier
- 1%Extreme weather
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,311 reported delay minutes here, that single category outweighs weather by 57 to one. The split is drawn from 4,311 reported delay minutes.
33% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,401 minutes out of 4,311, against a national NAS share of 21%.
Cancellations run at 5.52%, against 1.89% nationally. That is roughly one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
13.0% 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 361 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 76.4% on time across 163 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. 163 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 BWI to CLT
Put together: the delay figures matter less here than the 5.52% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 154 completed flights over 12 months sit behind that.
