These figures cover 337 flights between September 2025 and August 2026. The median arrival is 12 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.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 59% of the 2,884 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
59%
National Airspace System
26%
Carrier
15%

59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,884 reported delay minutes here, that single category outweighs weather by 59 to one. The split is drawn from 2,884 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 94.6% on time here.

Cancellations sit at 2.08% against a national 1.89%, which is ordinary. Diversions add another 0.30%.

Connections and stage length

What a delay here costs

5.5% 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 an hour, which a normal layover absorbs.

The 842 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.

The return leg is a different operation and performs like one: it runs 75.8% on time across 337 flights, 10 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 10 points of difference.

One caution: this is a thin sample. 337 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 TPA to BWI

Put together: treat all of this as provisional. 337 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 86.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 329 completed flights over 12 months sit behind that.
