Delta on JFK to TPA lands a B, 2 points 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 1,094 flights, with a median arrival 11 minutes early.

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

Carrier by carrier

Delta against every carrier on JFK to TPA

Delta flew 1,094 of the 2,310 flights on JFK to TPA, about 47% of it. Its 79.7% on time is 4 points better than the route as a whole, which runs 76.1%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Delta at 79.7% to Frontier at 69.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When Delta runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 19 points, against half a point between the best and worst carrier.

  • 8am–11am16 flights—

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 88.5% of the time, against 69.1% for the evening window. That is 19 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 349 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.May best, January worst

January is the weak month at 71.9% on time, against 90.2% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 93 flights.

Across the week, Wednesday is the strongest day at 92.2% on time and Sunday the weakest at 66.7%, a spread of 26 points.

Share of 1,060 completed flights by arrival against schedule.

43 of 190 late departures made up the time and arrived on time, 23% of them. In the other direction, 68 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 TPA.

The worst days

Worst days for Delta on JFK to TPA

The latest arrival of the period was on 17 March 2026, 7 hours 9 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).

Delay causes

Why Delta 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 15,000 reported delay minutes.

  • Carrier
    36%
  • Late-arriving aircraft
    32%
  • National Airspace System
    30%
  • Extreme weather
    1%
  • Security
    0%

The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,339 of the 15,000 delay minutes reported here. The split is drawn from 14,927 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 88.5% on time here.

Cancellations run at 2.74%, against 1.89% nationally. That is roughly one flight in 40 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

8.2% 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 1,005 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 82.3% on time across 1,094 flights, within 3 points 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. 1,094 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 Delta on JFK to TPA

Put together: treat all of this as provisional. 1,094 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 79.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,060 completed flights over 12 months sit behind that.
