Frontier on BWI to TPA sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land an hour and a half behind schedule. That rests on 337 flights, with a median arrival 9 minutes early.

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

The 8pm–5am window is where this operation falls apart: 54.1% on time, against 92.8% 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 11am–2pm window is the busiest, with 116 flights scheduled in it.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 55% of the 6,840 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
55%
Carrier
27%
National Airspace System
17%
Extreme weather
1%

55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,840 reported delay minutes here, that single category outweighs weather by 55 to one. The split is drawn from 6,840 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 92.8% on time here.

Cancellations run at 3.26%, against 1.89% nationally. That is about one flight in 30 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

9.8% 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.

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 86.0% on time across 337 flights, 10 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 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 BWI to TPA

Put together: the delay figures matter less here than the 3.26% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 326 completed flights over 12 months sit behind that.
