Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Frontier Airlines.

Frontier on RDU to TPA lands a B−, about a point better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 260 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 651 at 84.7% on time.

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

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 77% of the 4,329 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    77%
  • National Airspace System
    15%
  • Carrier
    7%

77% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,329 reported delay minutes here, that single category outweighs weather by 77 to one. The split is drawn from 4,329 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 84.6% on time here.

Cancellations run at 3.46%, 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

8.8% 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 a little over an hour, which a normal layover absorbs.

The 587 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 runs 78.2% on time across 260 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 260 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 TPA

Put together: the delay figures matter less here than the 3.46% cancellation rate. A late arrival costs you a little over an hour; 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. 251 completed flights over 12 months sit behind that.
